Stepping Motor Driver
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
