Stepping Motor Driver
LV8731V
Overview
The LV8731V is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step
drive and supports 4W 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.
BiCDMOS process IC
Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A)
Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 4W1-2 phase
Excitation step proceeds only by step signal input
Motor current selectable in four steps
Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated
Unusual condition warning output pins
No control power supply required
