DESCRIPTION

The DRV8812 provides an integrated motor driver solution for printers, scanners, and other automated

equipment applications. The device has two H-bridge drivers, and can drive a bipolar stepper motor or two DC

motors. The output driver block for each consists of N-channel power MOSFET’s configured as full H-bridges to

drive the motor windings. The DRV8812 is capable of driving up to 1.6-A of output current (with proper

heatsinking, at 24 V and 25°C).

A simple parallel digital control interface is compatible with industry-standard devices. Decay mode is

programmable.

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

lockout and overtemperature.

The DRV8812 is available in a 28-pin HTSSOP package with PowerPAD™ and in a 28-pin QFN package

PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
