LV8734V-MPB-H

LV8734V 系列 36 V 1.5 A 3.25 W 双通道 PWM 步进电机驱动器 - SSOP-44K

The LV8734V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports 2W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forward, reverse, brake, and standby of a motor. It is ideally suited for driving brushed DC motors and stepper motors used in office equipment and amusement applications.
