LV8741V-MPB-E

LV8741V 系列 6 V 1.5 A 550 mW 双通道 PWM 步进电机驱动器 - SSOP-44K

The LV8741V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and supports Quarter-step 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.
