STMicroelectronics L99H02XPTR, DC DC Motor Driver 36-Pin, PowerSSO-36 [L99H02XPTR]; 234-8879

The STMicroelectronics driver 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.
