DRV8834 Overview
The DRV8834 provides a flexible motor driver solution for toys, printers, cameras, and other mechatronic applications. The device has two Hbridge drivers, and is intended to drive a bipolar stepper motor or two DC motors. The output driver block of each H-bridge consists of N-channel power MOSFETs configured as an Hbridge to drive the motor windings.
