            DRV8885, 1.5 A Stepper Motor Driver
                    Texas Instruments offers its DRV8885, 1.5 A stepper motor driver with 1/16 microstepping and integrated current sensing
    

Image of Texas Instruments' DRV8885, 1.5 A Stepper Motor Driver Texas Instruments' 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 A_RMS output current (depending on proper PCB ground plane for thermal dissipation and at 24 V and T_A = 25°C).

The DRV8885's 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, over-current, short circuits, and over-temperature. Fault conditions are indicated by an nFAULT pin.
