7 Detailed Description
7.1 Overview
The DRV8833 device is an integrated motor driver solution for brushed DC or bipolar stepper motors. The device
integrates two NMOS H-bridges and current regulation circuitry. The DRV8833 can be powered with a supply
voltage from 2.7 to 10.8 V and can provide an output current up to 1.5-A RMS.
A simple PWM interface allows easy interfacing to the controller circuit.
The current regulation is a fixed frequency PWM slow decay.
The device includes a low-power sleep mode, which lets the system save power when not driving the motor.
