STMicroelectronics AEK-MOT-WINH92 Evaluation Board

STMicroelectronics AEK-MOT-WINH92 Evaluation Board is designed to lift the DC board driver based on the L99H92 gate driver and an external MCU. This board is configured to work with a single H-bridge for a bidirectional DC motor or two independent half-bridges for two unidirectional DC motors. The AEK-MOT-WINH92 board features an adjustable gain for anti-pinch and fulfilling any car window operative conditions. This compact-size board can be connected to any microcontroller easily, exploiting separate and dedicated connectors for SPI communication. The AEK-MOT-WINH92 board also offers three diagnostic features to detect potential short-to-ground, short-to-battery, and open load conditions when the device is in the off state.

Features

Up to 50A motor drive
Anti-pinch detection facilitated through programmable gain current sensing
In-line, low-side, and high-side current sensing options
Diagnostic pin to alert the microcontroller in case of faults, avoiding cyclic on-demand failure check via SPI, thus ensuring a prompt intervention
Reverse battery protection dedicated circuit
Low component count
Hosts the L99H92 H-bridge gate driver for DC automotive applications

Fault detection capabilities:
- Open-load, short-to-ground, and short-to-battery conditions
- Thermal warning and overtemperature shutdown
- Under/overvoltage protections
- Overcurrent protection
