Integrated Circuits (ICs) come in different forms and usually have one role to play – to improve the overall functions of the applications or devices. Today, these ICs have been modeled into different forms, with each of these variants offering unique attributes to the target applications.

One of such models is the digital isolator, of which the ADM3252EABCZ is one them. In this article, you will learn how this digital isolator works.

What is a Digital Isolator?

According to Digi-Key, a digital isolator is an electrically-separating Integrated Circuit (IC), which helps in transferring digital signals among the separated circuits.

You want to rely on ADM3252EABCZ to separate signals coming to the circuits, while maintaining the status quo of improving the workings of the target applications.

The Isolation in Force

Is there any need to isolate the electronic signals? Yes, it helps in keeping each of the circuits fully functional and independent.

For this to work effectively, ADM3252EABCZ has been optimized with a series of isolation technologies, one of which is the isoPower integrated technology. The highpoint of this technology is the support for Digital-to-Digital (dc-to-dc) conversion.

This is imperative, seeing that at the core of the isoPower technology is the separation or isolation of the circuits. Thus, it may be impossible for an analog circuit to interface with a digital circuit and vice-versa. Therefore, the dc-to-dc isolated converter is a welcome development.

The 3.3-V Logic Receiver

ADM3252EABCZ uses a variety of logics, one of which is the 3.3-V logic receiver. But before delving into this, we want to mention that this circuit isolator has a dedicated transmitter driver that converts the 3.3-volts logic input levels into the corresponding RS-232 output levels.

For the 3.3-volts logic receiver, it is tied to the EIA/TIA-232E specifications. As such, it provides for the acceptance of the RS-232 input levels via its dedicated inverting level shifter. This inverting level shifter is responsible for the translation or conversion of the RS-232 input levels into the corresponding 3.3-volts output levels.

ADM3252EABCZ’s 3.3-volts logic receiver also works well with the noise impedance, irrespective of the density. For example, its logic receiver uses the Schmitt trigger input with a hysteresis level of 0.1-volt to keep the noisy input and the slow transition input free from errors.

Overvoltage or an excessive supply of current could potentially reduce the potentials of a circuit. That is why the ADM3252EABCZ’s pull-down resistor measured at 5 kΩ is in place. It helps to protect the logic receiver against overvoltage, especially if it measures above ±30 V.

Data Rate

The speed of transferring data to, from and across the circuits is an important consideration when choosing a digital isolator. ADM3252EABCZ has an estimated data rate of 460 kilobytes per second. This is in conformation to the EIA/TIA-232E and the ITU-T V.28 specifications.

Although this is the maximum data rate, as per the datasheet, it is tied to one factor. For the data rate to clock up to that figure, it is expected that the higher data rates of 460 kbps are feasible, only when the ADM3252EABCZ is running at a reduced RS-232 capacitive load levels.

Below is a list of the additional technical specifications of this ADM3252EABCZ, represented in a table:

ADM3252EABCZ’s Power Transfer Process

Since ADM3252EABCZ uses the digital isolator framework and combines it with the magnetic coupling technology, how then does it transfer power?

The power, voltage or current transmission process is enabled by the isoPower technology. It uses a set of high-frequency switching elements to transfer, move or return power to the different “isolated” circuits. All these are done via the dedicated transformer.

The Commonplace for Total Isolation

Even though the separated circuits get power transmitted to and from them with ease, ADM3252EABCZ still maintains the isolation capabilities. To keep this running, it uses the chip-scale iCoupler technology to enable a total isolation solution. This isolation involves the separation or isolation of the dedicated dc-to-dc converter from the logic signals.

Digital Isolator Protection Features

ADM3252EABCZ complies with the Electrostatic Discharge (ESD) standards of protecting circuits, and in extension, consumer electronics.

The highpoint of the protection is the fine-tuning of the target device’s security framework in line with the IEC 61000-4-2 system-level testing specifications for ESD devices. The specifications highlight the subjection of the device to a system-level test to confirm the viability to survive normal operations.

To that end, both the Contact Discharge and the Air Gap Discharge have been designed to shore up these specifications.

ADM3252EABCZ uses these two discharge options to meet the ESD system-level testing specifications.

The Air Gap Discharge, according to Maxim Integrated, is a “method of testing ESD-protection structures in which the ESD generator is discharged through an air gap.”

Typically, the discharge takes place between the Device Under Test (DUT), which, in this case, is the ADM3252EABCZ; and the generator. Therefore, the DUT is to be placed close to the ESD test gun to confirm a discharge.

On the other hand, the Contact Discharge has to do with the ESD system-level testing that involves the discharge of the Electrostatic Discharge (ESD) pulse from the ESD test gun. The pulse is discharged directly to the Device Under Test (DUT).

By default, the ESD system-level testing process specifies the equivalenting of these discharge processes. For that purpose, the Level standard is used to make a Contact Discharge of 8 kV to be equivalent to the 15 kV Air Discharge.

That is exactly the ESD protection rating on ADM3252EABCZ. The Contact Discharge is pegged at ±8 kV, while the Air Discharge is pegged at ±15 kV.

Conclusion

ADM3252EABCZ isolates or separates circuits (electrically) to help them function independently, while using a total of 4 channels to switch the signals unidirectionally.

ADP5054ACPZ-R7 is a DC DC switching controller with a transistor driver output. In this article, we break down the concept of a DC DC switching controller and all the technical specifications of ADP5054ACPZ-R7.

How Does a DC DC Switching Controller Work?

DC DC switching controller is a type of Power Management Integrated Circuit (PMIC). The controller plays a significant role in consumer electronics by aiding the voltage regulation process.

Now, voltage or current can be excessive for a number of factors and it is the duty of the DC DC switching controller to keep the performance at the optimum. For this to work, the controller first generates the output supply voltages either below or above the input supply.

By doing that, it helps to balance the voltage of the high-efficient circuits at the best performance through the current alternation between the input and output voltages.

If you are using a DC DC switching controller, you can be sure that the excessive voltage will be regulated using different means. The processes include but are not limited to:

• Push-pull
• Buck-boost
• Half bridge
• Flyback
• SEPIC

ADP5054ACPZ-R7’s Features

ADP5054ACPZ-R7 packs a wide range of features or characteristics that make it one of the best DC DC switching controllers.

In this section, we are going to talk about some of these features.

1. Start Function

Voltage or current can be excessively “rushed into” the circuits depending on how the switching controller starts or boots. That is the reason why ADP5054ACPZ-R7’s start function combines a variety of functions.

First, there is the precharged start-up feature, which prevents the low-side FETs from getting damaged during the boot process.

Second, a majority of ADP5054ACPZ-R7’s buck regulators use a soft start circuitry, which aids in limiting the current of flow of voltage once the controller is started.

2. Direct Connection to High-Input Voltages

ADP5054ACPZ-R7 is by default, equipped with four (4) high-performance buck regulators. These regulators are packed in a 48-lead LFCSP package.

In addition to the optimization according to board space requirements and system performance, the regulators also establish a direct connection without using any of the preregulators. The outcome? A seamless connection to the high-input voltages, up to 15.5 volts.

3. Power Savings Mode (PSM)

Conserving power is also a part of the features that set ADP5054ACPZ-R7 apart from the other DC DC switching controllers.

The Power Savings Mode (PSM) works by enabling a smooth transition of the buck regulators to the variable frequency.

Note that the Power Savings Mode (PSM) is typically activated when the output of the controller falls below the preset or predefined value/threshold of the PSM.

The activation of the Power Savings Mode (PSM) enables the buck regulators to remain the mode for a few oscillator cycles. The buck regulators would only be taken out of the PSM and restored to the default settings after voltage increases to the PSM’s threshold.

4. Technical Specifications

The table below shows some of the technical attributes of the ADP5054ACPZ-R7 DC DC switching controller:

5. ADP5054ACPZ-R7’s Transistor Driver Output

ADP5054ACPZ-R7 uses a transistor driver as the output and this section is dedicated to explaining how it works.

A transistor driver is generally viewed as a “current amplifier” in the sense that it magnifies or increases the current in any consumer electronics or circuit it is placed. It is typically used to “drive” or provide sufficient current to the target device without necessarily amplifying or increasing the voltage.

Transistor drivers are also designed to drive the “high-power applications,” thus, increasing the performance in the process. To that end, you can expect the transistor to get hotter at some point.

A better way to tackle the excessive heat is to use a thermal transfer compound paste, which helps in improving the heatsink’s efficiency.

You should also consider installing a heatsink. Attaching the heatsink to the transistor’s tab helps in cooling it when it gets hotter.

Important Considerations for the ADP5054ACPZ-R7 DC DC Switching Controller

Before you are sold on the idea of getting the ADP5054ACPZ-R7, we would like to make a few more submissions.

These are some of the additional considerations you may want to make before deciding to get the switching controller:

Thermal Shutdown Capabilities

Everything is not left to chance, as far as the ADP5054ACPZ-R7 is concerned. It keeps the power optimum, while ensuring that the heat dissipation is excellent.

It also has a thermal shutdown capability, designed to oversee the shutting down of the IC. The thermal shutdown feature kicks in when the junction temperature goes above 150˚C.

The junction temperature tends to shoot above the recommended temperature of 150˚C only when certain factors come to play. From the increase in the ambient temperature to a higher current operation and a poor circuit board design; these factors can negatively impact the junction temperature.

Now, when the junction temperature goes above 150˚C, the Thermal Shutdown (TSD) circuit would then kick in to regulate it. The regulation is done in the form of turning off the Integrated Circuit (IC), while keeping the internal linear regulator on.

However, ADP5054ACPZ-R7 is not quick to restore the circuit to operation until certain measures have been put in place. The first measure is to integrate a 15˚C hysteresis to prevent the circuit board from returning to the normal operations.

Once that is done, the ADP5054ACPZ-R7 wouldn’t become operational, until the on-chip temperature has fallen below 135˚C.

It is only when this has been attained that the ADP5054ACPZ-R7 would initiate the soft start function to slowly activate the circuit for operations after exiting the Thermal Shutdown (TSD) mode.

Precision Enabling

ADP5054ACPZ-R7 has a precision enable pin on each of the channels. The pin, among many other things, aid the power-up sequencing of the circuit board.

Final Words

ADP5054ACPZ-R7 uses the DC DC switching controller to regulate (excessive) voltage, protect the circuit and balance the performance of the components.

Analog Devices Incorporated (ADI), a leading manufacturer of programmable devices has AD7606BBSTZ-RL on its list of products. It is a 64-lead LQFP FPGA, designed to be a special purpose Data Acquisition System (DAS).

In case you are wondering what a DAS means, how the AD7606BBSTZ-RL functions and every other thing about the FPGA, we answer your questions in this article. In this article, we cover the properties of the AD7606BBSTZ-RL, explain how a DAS functions and compared the ADC and the DAC operations of the circuit.

How does AD7606BBSTZ-RL Function?

Primarily, it is a Field Programmable Gate Array (FPGA) optimized for special purpose or most relevant uses, ranging from analog and digital conversion and providing flexible interfacing.

The AD7606B Family

AD7606BBSTZ-RL belongs to the broader AD7606B family of Field Programmable Gate Arrays (FPGAs). The latter is an 8-channel Data Acquisition System (DAS) with a 16-bit resolution and simultaneous sampling of the Analog-to-Digital Converter (ADC).

AD7606B also provides an 800 kSPS Bipolar Input, which doubles as the sampling rate for the circuit board.

Below are some of the additional properties of AD7606BBSTZ-RL’s family of FPGAs:

1. Monitoring Properties

It is not very often that Field Programmable Gate Arrays (FPGAs) break down or start to malfunction. But when they do, it could be because of a combination of factors, ranging from oversight during the design process and the inability to detect faults earlier.

Either of these two, if left unattended to, could make major damages in the Integrated Circuit. However, the chances of getting damaged is reduced with AD7606BBSTZ-RL’s monitoring and self-diagnostics properties.

These properties combine to help the circuit discover potential threats to the operation and make real-time alerts in that regard.

2. Advanced Error Detection Capabilities

Detecting errors and design challenges is not limited to the monitoring properties. It also has a wide range of advanced error detection capabilities, ranging from:

• ±21 V input clamp protection with an 8 kV ESD
• Analog input open circuit detection feature
• CRC error-checking on both the registers and the read/write data.

3. AD7606B Supports Extra Modes

Looking for an FPGA with multiple modes? Look no farther than the AD7606BBSTZ-RL. It typically supports the hardware mode, which is compatible with the AD7606 device. However, you can also access other modes if you switch to the software mode.

Examples of the additional features supported in the software mode are:

• Diagnostic multiplexer
• An additional ±2.5-volt Analog Input Range.
• Monitoring functions, such as overvoltage and undervoltage events, Serial Peripheral Interface (SPI) invalid read/write, reset detection, and Cyclic Redundancy Check (CRC). The other is the busy truck monitor.

Technical Properties of the AD7606BBSTZ-RL

Below is a table, representing the technical properties of the AD7606BBSTZ-RL Data Acquisition System (DAS):

AD7606BBSTZ-RL’s Power Line Improvement Capabilities

At the core of AD7606BBSTZ-RL functionalities is the improvement of the power or current capabilities of the target devices. Worthy of mentioning here is that the manufacturer (Intel) places a premium on improving the functions of the applications that rely on power lines.

What exactly are power lines and what role do they play? To put it simply, power lines are the dedicated current lines that use a combination of resistor divider networks and current transformers to detect the neutral currents, voltages and the major phases in an electronic device.

Therefore, the delegation of the AD7606BBSTZ-RL to that end helps to fast-track those capabilities, while creating additional connections in the process. The external connection creation is done via the AD7606B FPGA capabilities, involving the use of a high-input impedance to establish a direct interface to a sensor. In turn, this pathway paves the way for the AD7606BBSTZ-RL’s Data Acquisition System (DAS) to provide all required building blocks.

Complete Power Line Development

You can also count on the AD7606BBSTZ-RL to build a solid power line, which facilitates the Data Acquisition System (DAS) process.

For emphasis, the power line development involves a combination of the following:

• A 21-volt analog input clamp protection.
• Low drift 2.5-volt reference
• A resistive programmable gain amplifier with 5 MΩ input impedance.
• An optional digital averaging filter up to 256 of oversampling ratios.
• A first-order antialiasing filter.

Sensor Disconnect Detection

One or more components or parts disconnecting from an FPGA can impact its performance. It is better to have facilities in place to detect these disconnections, even before they happen. That is what the sensor disconnect detection peripheral of the AD7606BBSTZ-RL does.

The idea is to use the traditional pull-down resistor alongside the sensor. The combination of the two allows the users (or the digital circuit designer) to find out in real-time, when any of the sensors disconnect.

The easiest way to detect the disconnection, as per the default configuration, is by monitoring when the output code of the Analog-to-Digital Converter (ADC) drops below 20 LSBs. It is also important to wait for confirmation by checking for a repeat of a number of samples (N) of the same detection.

AD7606BBSTZ-RL’s Direct Sensor Interface

The Direct Sensor Interface, is no doubt, one of the most important attributes of the AD7606BBSTZ-RL. The default design is to increase AD7606BBSTZ-RL’s input impedance; a configuration that allows the FPGA to make real-time interface connection to the supported sensors.

The Direct Sensor Interface also has a role to play in fault detection, especially in the area of decreasing the offset to enable the quicker detection of the sensor detection.

It also helps in reducing the dominance of the gain error, which a variety of external series of resistors introduce to the FPGA.

Final Thoughts

AD7606BBSTZ-RL is to be used for “special purpose” designs, especially those requiring the inputs of a Data Acquisition System (DAS).

Lamination Process Using the Megtron 7 PCB Laminates

You’ll utilize the Megtron 7 PCB laminates in holding the PCB layers altogether tightly ensuring an effective insulation in-between the layers.

Below is the process to follow

Preparation Stage

First, you must wash the panels and then remove the copper surfaces that are corroded as well as possible fingerprints. Asides from this, washing gets rid of the dry fill residues, carbonate residues, and antifoam from the stripping (dry film)

Micro-etching

Apply the condition of having homogenous and appropriate brown or black oxide treatment. Also, it helps in reducing the copper thickness from 0.2 to 0.1 micrometers. After this, you’ll perform your black oxide treatment, which offers better adhesion to prevent delamination issues.

Lamination Process

Here, you will be arranging all the layers altogether and then make sure that they don’t move when the lamination process is on. This panel is then complete with some copper foils attached to the bottom and top and then prepregs present on its outer layers.

You’ll place it in the lamination machine and then under extremely high pressure and temperature. The inner pressure of the machine is about 180 tons for every square meter, while the process of lamination will take around 2 hours.

Then cure it under some high temperatures, and then cool it while releasing the pressure. This step completes the lamination process
