常备库存 PT2474 普诚科技 双极型步进电机驱动器

DESCRIPTION

The PT2474 is a dual channel H-bridge motor driverthat operates on wide supply voltage range from 4Vto 16V. The control logic pins have built-in phasegenerator function; it could drive a four-wire bipolarstepping motor with only 2 input pins. The inputwaveform is generates by the external MCU andphase relation between two input pins is a standardfull-step excitation.

FEATURES

● Wide Supply Voltage Range: 4V to 16V
