DESCRIPTION
The DRV8814 provides an integrated motor driver solution for printers, scanners, and other automated
equipment applications. The device has two H-bridge drivers, and is intended to drive DC motors. The output
driver block for each consists of N-channel power MOSFET’s configured as H-bridges to drive the motor
windings. The DRV8814 can supply up to 2.5-A peak or 1.75-A RMS output current (with proper heatsinking at
24 V and 25°C) per H-bridge.

A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is
programmable to allow braking or coasting of the motor when disabled.
