Overview
The L99MD02XPTR, produced by STMicroelectronics, is a hexa half-bridge driver IC designed specifically for automotive applications. This device is intended to drive DC motors and can manage up to six half-bridge configurations. It allows for the simultaneous control of three DC motors or the sequential control of up to five DC motors. The L99MD02XPTR features an integrated 24-bit standard serial peripheral interface (SPI) for controlling all outputs and providing diagnostic information such as normal operation, open-load in on-state, overcurrent, temperature warning, and overtemperature protection.
