Image of Texas Instruments' DRV8886, 2 A Stepper Motor Driver Texas Instruments' DRV8886 is a stepper motor driver for industrial and consumer end equipment applications. The device is fully integrated with two N-channel power MOSFET H-bridge drivers, a microstepping indexer, and integrated current sensing. The DRV8886 is capable of driving up to 2 A full scale or 1.4 A rms output current (24 V and T_A = 25°C, dependent on PCB design).

The DRV8886 uses an internal current sense architecture to eliminate the need for two external power sense resistors, saving PCB area and system cost. The DRV8886 uses an internal fixed off-time PWM current regulation scheme adjustable between slow and mixed decay options.

A simple STEP/DIR interface allows an external controller to manage the direction and step rate of the stepper motor. The device can be configured in different step modes ranging from full-step to 1/16 microstepping. A low-power sleep mode is provided for very low standby quiescent standby 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 nFAULT pin.
