LV8734V Overview
.DataSheet.co.kr Ordering number : ENA1824A LV8734V Overview Bi-CMOS LSI PWM Constant-Current Control Stepping Motor Driver The LV8734V is a 2-channel H-bridge driver IC that can switch a stepping 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...
LV8734V Key Features
- Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated
