3 Description

The DRV8828 provides an integrated motor driver

solution for printers, scanners, and other automated equipment applications. The device has one H-bridge

driver, and can drive one winding of a bipolar stepper

motor or one DC motor. The output driver block

consists of N-channel power MOSFET’s configured

as a full H-bridge to drive the motor winding. The

DRV8828 is capable of driving up to 3-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

overcurrent protection, short circuit protection,

undervoltage lockout and overtemperature.

The DRV8828 is available in a 28-pin HTSSOP

package with PowerPAD™ (Eco-friendly: RoHS & no

Sb/Br).
