LV8740V
Overview
PWM Current Control Stepping Motor Driver
The LV8740V is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step drive and supports W 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 stepping motors used in office equipment and amusement applications.
Features
- Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated.
- On resistance (upper side : 0.3Ω ; lower side : 0.2Ω ; total of upper and lower : 0.5Ω ; Ta = 25°C, IO = 2.5A)
- Excitation mode can be set to 2-phase, 1-2 phase full torque, 1-2 phase or W1-2 phase
- Excitation step proceeds only by step signal input
- Motor holding current selectable in four steps
- BiCDMOS process IC
- Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated
- Unusual condition warning output pins
- Supports control power...
