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 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 DRV8825 can supply up to 2.5-A peak or 1.75-A RMS 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 DRV8825 is available in a 28-pin HTSSOP package with PowerPAD™ (Eco-friendly: RoHS & no Sb/Br).
