Description

The L99MD01 is an octal half-bridge driver for

automotive applications.

The device is intended to drive DC and/or stepper

motors. Using the boost converter it’s possible to

drive 4 stepper motors simultaneously. Without

boost converter the system is able to run 3

stepper motors in sequential mode or 2 stepper

motors simultaneously. The octal half bridge

configuration allows also to drive 4 DC-motors

simultaneously and 7 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.
