SLVSA73F – APRIL 2010 – REVISED JULY 2014 DRV8825 Stepper Motor Controller IC
1 Features 3 Description 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 25В°C). 1 PWM Microstepping Stepper Motor Driver
– Built-In Microstepping Indexer
– Up to 1/32 Microstepping
Multiple Decay Modes
– Mixed Decay
– Slow Decay
– Fast Decay …
