Texas Instruments DRV8703QRHBRQ1

The DRV870x-Q1 family of devices is a single H-bridge gate driver that uses four external N-channel MOSFETs targeted to drive a bidirectional brushed-DC motor.

A PH/EN, independent H-Bridge, or PWM interface allows simple interfacing to controller circuits. An internal sense amplifier provides adjustable current control. The gate driver includes circuitry to regulate the winding current using fixed off-time PWM current chopping.

The DRV870x-Q1 family of devices drives both high-side and low-side FETs with a 10.5-V VGS gate drive. The gate-drive current for all external FETs is configurable with a single external resistor or through the serial peripheral interface (SPI).

A low-power sleep mode is provided which shuts down internal circuitry to achieve a very-low
quiescent-current draw.
