The roof module motor driver supplies the drive voltage and current to the sun roof motor, typically a brushed DC motor.
The DRV870x-Q1 family of devices is a single Hbridge gate driver that uses four external N-channel MOSFETs targeted to drive a bidirectional brushedDC 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 highside 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.
