Description for the DRV8886AT

The DRV8886AT is a stepper motor driver for industrial and consumer end equipmentapplications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, amicrostepping indexer, and integrated current sensing. The DRV8886AT is capable of driving up to2-A full scale or 1.4-A rms output current (24-V and TA = 25°C, dependent onPCB design).

The DRV8886AT uses an internal current sense architecture to eliminate the need for twoexternal power sense resistors saving PCB area and system cost. The DRV8886AT uses an internal PWMcurrent regulation scheme adjustable between smart tune adaptive decay technology, slow, and mixeddecay options. Smart tune adaptive decay technology automatically adjusts for optimal currentregulation performance and compensates for motor variation and aging effects.

A simple STEP/DIR interface allows an external controller to manage the direction andstep rate of the stepper motor. The device can be configured in different step modes ranging fromfull-step to 1/16 microstepping. A low-power sleep mode is provided for very low standby quiescentstandby current using a dedicated nSLEEP pin.

Device protection features are provided for supply undervoltage, charge pump faults,overcurrent, short circuits, and overtemperature. Fault conditions are indicated by the nFAULTpin.
