The DRV8814 provides an integrated motor driver solution for printers, scanners, and other automated
equipment applications. The device has one H-bridge driver, and is intended to drive one DC motor. The device
has two H-bridge drivers, and is intended to drive two 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).
