A3981 - Automotive Programmable Stepper Driver
TheA3981 is a flexible microstepping motor driver with built-in translator for easy operation.
It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and sixteenth-step modes, at up to 28 V and ±1.4 A.
The A3981 can be controlled by simple Step and Directi
