L99H02QFTR

L99H02QFTR is a H-bridge gate driver for automotive applications. 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. Application includes wiper, power door, seat belt tensioner, seat positioning, valve tronic, park break, 2H motors.
