DRV8703DQRHBRQ1

具有 SPI 控制功能的汽车类 45V、半桥智能栅极驱动器 32-VQFN -40 to 125

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 loads.

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.

The DRV870xD-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.
