The DRV870xD-Q1 family of devices is a half-bridge gate driver that uses
two external N-channel MOSFETs targeted to drive unidirectional brushed-DC motors or solenoid
The 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.
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
