DRV8885 Overview
The DRV8885 is a stepper motor driver for industrial equipment applications. The device has two Nchannel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sense. The DRV8885 is capable of driving up to 1.5 A full scale or 1.0 A rms output current (depending on proper PCB ground plane for thermal dissipation and at 24 V and TA = 25°C).
