Pinout
Pin Functions:
1. VCC (Pin 1): Supply voltage for the device.
2. OUT1 (Pin 2): H-bridge output 1, connected to the motor.
3. OUT2 (Pin 3): H-bridge output 2, connected to the motor.
4. GND (Pin 4): Ground connection for the device.
5. IPROPI (Pin 5): Current sense output pin (current proportional output).
6. IN1 (Pin 6): Input control for OUT1.
7. IN2 (Pin 7): Input control for OUT2.
8. nSLEEP (Pin 8): Sleep mode input; active low to enter low-power state.
The DRV8871DDARQ1 can control the direction and speed of a brushed DC motor by controlling the logic inputs (IN1, IN2) and provides current sensing through the IPROPI pin.
