The DRV8881 is a bipolar stepper or brushed-DC motor driver for industrial applications.The device output stage consists of two N-channel power MOSFET H-bridge drivers. The DRV8881 iscapable of driving up to 2.5-A peak current or 1.4-A rms current per H-bridge (with proper PCBground plane for thermal dissipation and at 24 V and TA = 25°C).

Smart tune automatically tunes motors for optimal current regulation performance andcompensates for motor variation and aging effects. Smart tune is available on the DRV8881E.Additionally, slow, fast, and mixed decay modes are available.

The PH/EN (DRV8881E) or PWM (DRV8881P) pins provide a simple control interface. Aninternal sense amplifier allows for adjustable current control. A low-power sleep mode is providedfor very-low quiescent current standby 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.
