ADA4523-1

• Full featured evaluation board for the ADA4523-1
• Enables efficient prototyping
• User defined circuit configuration
• Edge mounted SMA connector provisions
• Shutdown function for low power application

The EVAL-ADA4523-1BRMZ allows the evaluation of the ADA4523-1 single-channel, 8‑lead, micro small outline package (MSOP) operational amplifier. The ADA4523-1 in this evaluation board is configured as a noninverting amplifier with a gain of 101. The ADA4523-1 has a typical gain bandwidth product of 4 MHz. When using a gain of 101, the useable bandwidth of the ADA4523-1 is limited to approximately 39.6 kHz. This limitation in bandwidth acts as a low-pass filter that rejects the artifacts generated by the 330 kHz internal chopping frequency of the ADA4523-1.

The EVAL-ADA4523-1BRMZ layout lessens the thermocouple effects of the trace and components that introduce offset voltages greater than the maximum offset voltage of the ADA4523-1 by carefully constructing the nodes connected to the inverting and noninverting inputs. The ADA4523-1 also features a shutdown mode for low power applications. Test point provisions for the SD and SD_COM pins are placed on the EVAL-ADA4523-1BRMZ to easily use the shutdown function.

The EVAL-ADA4523-1BRMZ mainly consists of 0805 sized resistors and capacitors to ensure simple installation except for the bypass capacitors. The 10 μF bypass capacitors (C1 and C4) have a 2220 package size to accommodate a higher voltage rating because the ADA4523-1 has a maximum supply of 55 V.

For full details on the ADA4523-1, see the ADA4523-1 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADA4523-1BRMZ.

• Complete reference design for Type 2 EVSE Cordset (IC-CPD)
• Power level from 2.3 kW up to 3.6 kW
• Designed to comply with the applicable standards - IEC61851, IEC62752
• Incorporates a 6 mA DC/30 mA rms RCD and a control pilot circuit
• Stuck relay detection and relay state of health
• Overtemperature detection
• Integrated isolation
• Reduced component count for cost optimization
• Bluetooth 5.2 interface for connectivity to external devices
• Open-source software stack to enable custom firmware development

The AD-ACEVSECRDSET-SL is a complete Type 2 EVSE 3.6 kW charging cable solution, providing a reference design intended for evaluation and prototyping of electric vehicle (EV) charging systems.

The system includes a 3-channel isolated sigma-delta (Σ-Δ) ADC for voltage and current measurement on the single-phase power input and measurement of the relay voltage for solder contacts detection and relay state of health. Safe operation is enabled by the inclusion of a 6 mA DC / 30 mA rms RCD. Detection of overvoltage, undervoltage, overcurrent, overtemperature and EV diode presence is also available.

A MAX32655 low-power, ARM^® Cortex^®-M4 Microcontroller implements the logic for system control and communication with the EV over the control pilot interface. A programming and debugging interface are included. The MAX32655 Bluetooth 5.2 interface enables connectivity to external devices.

The design is accompanied by an open-source software stack and reference applications, enabling custom software development to start from a proven implementation validated to meet the applicable standards. An external programmer such as the MAX32625PICO MAXDAP Programming Adapter, or any other similar programmer supporting the SWD interface, is required to enable firmware programming and debug.

The system is designed to comply with the IEC61851 and IEC62752 standards.
