DESCRIPTION

The DRV8824 provides an integrated motor driver solution for printers, scanners, and other automated

equipment applications. The device has two H-bridge drivers and a microstepping indexer, and is intended to

drive a bipolar stepper motor. The output driver block for each consists of N-channel power MOSFET’s

configured as full H-bridges to drive the motor windings. The DRV8824 is capable of driving up to 1.6-A of output

current (with proper heatsinking, at 24 V and 25°C).

A simple step/direction interface allows easy interfacing to controller circuits. Pins allow configuration of the

motor in full-step up to 1/32-step modes. Decay mode is programmable.

Internal shutdown functions are provided for overcurrent protection, short circuit protection, undervoltage lockout

and overtemperature.

The DRV8824 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
