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.

Internal shutdown functions are provided for over current protection, short circuit protection, under voltage

lockout and overtemperature.

TheDRV8814 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
