Product overview

Description

The L99H01 is designed to control 4 externalN-channel MOS transistors in 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 all outputs and provides diagnostic information. An interface pin for the thermal sensors of the external MOSFETs is implemented.
