Texas Instruments  DRV8880RHRT

The DRV8880 is a bipolar stepper motor driver for industrial applications. The device hastwo N-channel power MOSFET H-bridge drivers and a microstepping indexer. The DRV8880 is capable ofdriving 2.0 A full-scale current or 1.4-A rms current (with proper PCB ground plane for thermaldissipation and at 24 V and TA = 25°C).

AutoTune™ automatically tunes stepper motors for optimal current regulation performanceand compensates for motor variation and aging effects. Additionally slow, fast, and mixed decaymodes are available.

The STEP/DIR pins provide a simple control interface. The device can be configured infull-step up to 1/16- step modes. A low-power sleep mode is provided for very low quiescent currentstandby 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 a nFAULTpin.
