STMicroelectronics L99H02QFTR, 48 mA, 6 → 28V 32-Pin, LQFP32

The STMicroelectronics H-bridge gate driver is designed to drive 4 external N-channel MOS transistors 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.
