7.1 Overview

The DRV8832-Q1 is an integrated motor driver solution used for brushed motor control. The device integrates one H-bridge, current regulation circuitry, and a PWM voltage regulation method.

Using the PWM voltage regulation allows the motor to maintain the desired speed as VCC changes. Battery operation is an example of using this feature. When the battery is new or fully charged VCC will be higher than when the battery is old or partially discharged. The speed of the motor will vary based on the voltage of the battery. By setting the desired voltage across the motor at a lower voltage, a fully charged battery will use less power and spin the motor at the same speed as a battery that has been partially discharged.
