AD-ACEVSECRDSET-SL

Type 2 EVSE 3.6 kW Charging Cable

Buy Now View Details

Features and Benefits

  • 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

Product Details

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.

SCP-LT8330-EVALZ

LT8330 Signal Chain Evaluation Board | Boost Converter w/ 1A, 60V Switch

Buy Now View Details

Product Details

Demonstration circuit SCP-LT8330-EVALZ features the LT8330, a boost/SEPIC/inverting converter with a 1A, 60V switch. The demo circuit is specifically a boost converter with an operating input voltage range from 10V to 36V and an output voltage of 48V. With a 12V input, the maximum output current is 135mA.

Like all boards in the Signal Chain Power series, this board is designed to be easily plugged into other SCP boards to form a complete signal chain power system, enabling fast evaluation of low power signal chains. To evaluate this board, some universal SCP hardware is required, namely:

  • SCP-INPUT-EVALZ
  • SCP-OUTPUT-EVALZ
  • SCP-FILTER-EVALZ
  • SCP-THRUBRD-EVALZ
  • SCP-1X2BKOUT-EVALZ
  • SCP-1X5BKOUT-EVALZ
  • SCP-5X1-EVALZ

 

To properly evaluate SCP series demo boards, you will need the SCP Configurator companion software. SCP Configurator can help you choose the right board and topology for your design.

Note that the Demo Manual does not cover details important to the operation and configuration regarding the LT8330. Please refer to the LT8330 datasheet for a complete description of the part.

Product Details

Demonstration circuit 2018A features the LT8330, a low IQ boost/SEPIC/inverting converter with a 1A, 60V switch.


The LT8330 allows higher input and output voltages than comparable converters and also significantly reduces input current at light loads and no load. The LT8330 regulates either positive or negative outputs and has an internally programmed switching frequency of 2MHz.
