Texas Instruments DRV8881 2A Stepper Motor Driver 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 is capable of driving up to 2.5A peak current or 1.4A rms current per H-bridge (with proper PCB ground plane for thermal dissipation and at 24V and TA = 25°C). AutoTune™ automatically tunes motors for optimal current regulation performance and compensates for motor variation and aging effects. The PH/EN (DRV8881E) or PWM (DRV8881P) pins provide a simple control interface. An internal sense amplifier allows for adjustable current control. A low-power sleep mode is provided for very-low quiescent current standby using a dedicated nSLEEP pin.
