Description

The L99H02 is designed to drive 4 external

N-channel MOS transistors in H-bridge

configuration for DC-motor driving in automotive

applications. A free configurable current sense

amplifier is integrated. The integrated standard

serial peripheral interface (SPI) controls the

device and provides diagnostic information. An

interface pin for the thermal sensors of the

external MOSFETs is implemented.
