Texas Instruments DRV8885 1.5A Stepper Motor Driver is a stepper motor driver for industrial equipment applications. The device has two N-channel power MOSFET H-bridge drivers, a micro-stepping indexer, and an integrated current sense. The DRV8885 is capable of driving up to 1.5A full scale or 1.0Arms output current. The Texas Instruments DRV8885 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 under-voltage, charge pump faults, overcurrent, short circuits, and overtemperature. Fault conditions are indicated by an nFAULT pin.
