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.
