6.3.1 H-Bridge Gate Driver

The DRV8762-Q1 integrates two, half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The bootstrap circuit provides the correct gate bias voltage to the high-side MOSFET across a wide operating condition, and an integrated trickle charge pump supports 100% duty cycle operation. The half-bridge gate drivers can be used in combination to drive a single motor or separately to drive other types of loads.
