A4993 Automotive Stepper Driver

The A4993 is a flexible microstepping motor driver with integrated phase current control and a built-in translator for easy operation. It is a single chip solution designed to operate bipolar stepper motors in full-, half-, quarter-, eighth-, and sixteenth-step modes, at up to 28 V. At power-on, the.
