Texas Instruments DRV8885PWPR DRV8885PWPR Motor Driver Stepper 8V to 37V Supply 1A/1 Output HTSSOP-24

The DRV8885PWPR is a 1.5A stepper motor driver with 1/16 microstepping and integrated current sensing in 24 pin HTSSOP package. 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 1.5A full scale or 1A rms output current. The 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 undervoltage, charge pump faults, overcurrent, short circuits and overtemperature. Fault conditions are indicated by an nFAULT pin.
