DRV8825 Datasheet – Stepper Motor Controller IC – TI

Part Number : DRV8825, DRV8825PWPR

Function : Stepper Motor Controller IC

Package : HTSSOP 28 Pin Type

Manufacturers : Texas Instruments




The DRV8825 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 consists of N-channel power MOSFET’s configured as full H-bridges to drive the motor windings. The DRV8825 is capable of driving up to 2.5 A of current from each output (with proper heat sinking, at 24 V and 25°C).
