Description
The L99MD02 IC is a 6 x half bridge driver for
automotive applications. The device is intended to
drive DC-motors. It is possible to drive 3
DC-motors simultaneously or up to 5 DC-motors
sequentially.
The integrated 24 bit standard serial peripheral
interface (SPI) controls all outputs and provides
diagnostic information: normal operation,
open-load in on-state, overcurrent, temperature
warning and overtemperature.
