Bi-CMOS LSI
PWM Constant-Current Control
Stepping Motor Driver
LV8746V
Overview
The LV8746V is a stepping motor driver corresponding to the W1-2 aspect excitation drive that the selection of CLK-IN
input and a parallel input is possible. It is ideally suited for driving brushed DC motors and stepping motors used in office
equipment and amusement applications.
Features
PWM current control stepping motor driver incorporated.
BiCDMOS process IC
Low on resistance (upper side : 0.84Ω ; lower side : 0.7Ω ; total of upper and lower : 1.54Ω ; Ta = 25°C, IO = 1A)
Excitation mode can be set to 2-phase, 1-2 phase Full torque, 1-2 phase, or W1-2 phase
CLK-IN input and a parallel input can be selected.
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
