A3967 Description
The A3967 is a plete microstepping motor driver with built-in translator. It is designed to operate bipolar stepper motors in full-, half-, quarter-, and eighth-step modes, with output drive capability of 30 V and ±750 mA. The A3967 includes a fixed off-time current regulator that has the ability to operate in slow, fast, or mixed current-decay modes.
