Texas Instruments DRV8884 1.0A Stepper Motor Driver
Texas Instruments DRV8884 1.0A Stepper Motor Driver is a stepper motor driver designed 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 DRV8884 is capable of driving up to 1.0A full scale or 0.7Arms output current. The Texas Instruments 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.Features
