            DRV8880, 2 A Stepper Motor Driver
                    Texas Instruments offers its DRV8880, 2 A stepper motor driver with 1/16 microstepping indexer and AutoTune™
    

Image of Texas Instruments' DRV8880 2 A Stepper Motor Driver Texas Instruments' DRV8880 is a bipolar, stepper motor driver for industrial applications. The device has two N-channel, power MOSFET, H-bridge drivers and a microstepping indexer. The DRV8880 is capable of driving 2.0 A full-scale current or 1.4 A rms current (with proper PCB ground plane for thermal dissipation and at 24 V and T_A = 25°C).

AutoTune automatically tunes stepper motors for optimal current-regulation performance and compensates for motor variation and aging effects. Slow, fast, and mixed decay modes are also available.

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-circuit, and over-temperature. Fault conditions are indicated by an nFAULT pin.
