说明

The DRV8832 provides an integrated motor driver solution for battery-powered toys, printers, and other low-voltage or battery-powered motion control applications. The device has one H-bridge driver, and can drive one DC motor or one winding of a stepper motor, as well as other loads like solenoids. The output driver block consists of N-channel and P-channel power MOSFET’s configured as an H-bridge to drive the motor winding.

Provided with sufficient PCB heatsinking, the DRV8832 can supply up to 1-A of continuous output current. It operates on power supply voltages from 2.75 V to 6 V.

To maintain constant motor speed over varying battery voltages while maintaining long battery life, a PWM voltage regulation method is provided.
