The DRV8885 is a stepper motor driver for industrial equipment applications. The device
has two N-channel 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).
The DRV8885 integrated current sense functionality eliminates the need for two external
The STEP/DIR pins provide a simple control interface. The device can be configured in
full-step up to 1/16 step modes. A low-power sleep mode is provided for very-low quiescent current
standby using a dedicated nSLEEP pin.
Internal protection functions are provided for undervoltage, charge pump faults,
overcurrent, short circuits, and overtemperature. Fault conditions are indicated by an nFAULT
