The PT2474 is a dual channel H-bridge motor driver that operates on wide supply voltage range from 4V to 16V. The control logic pins have built-in phase generator function; it could drive a four-wire bipolar stepping motor with only 2 input pins. The input waveform is generates by the external MCU and phase relation between two input pins is a standard full-step excitation.
