The DRV8884 device 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 DRV8884 is capable of driving up to 1.0-A full scale or 0.7-A rms output current (depending on proper PCB ground plane for thermal dissipation and at 24 V and TA = 25°C).

The DRV8884 integrated current sense functionality eliminates the need for two external sense resistors.

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 pin.
