LV8740V-TLM-E
数据手册.pdfLV8740V 系列 38 V 2.5 A 3.45 W 双通道 PWM 步进电机驱动器 - SSOP-44J
The LV8740V 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 DC 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.
