Features: Simple step and direction control interface, short-to-ground and shorted-load protection. Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay). Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption.
