STMicroelectronics L99H02 H-Bridge Gate Driver
STMicroelectronics L99H02 H-Bridge Gate Driver is designed to drive four external N-channel MOS transistors in H-bridge configuration for DC-motor driving in automotive applications. A free configurable current sense amplifier is integrated into the STMicroelectronics L99H02. 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.
