Product Overview
LV8741V: PWM Current Control Stepper Motor Driver
For complete documentation, see the data sheet.
The LV8741V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which is capable of micro-step drive and
supports Quarter-step 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 stepper motors used in office equipment and amusement
applications.
Features
• On resistance (upper side : 0.5Ω ; lower side : 0.5Ω ; total of
upper and lower : 1.0Ω ; Ta = 25°C, IO = 1.5A)
• Excitation mode can be set to Full-step, Half-step full torque,
Half-step or Quarter-step
• Motor current selectable in four steps
• Output short-circuit protection circuit (selectable from latch-
type or auto reset-type) incorporated
• Thermal shutdown circuit and power supply monitor circuit
incorporated
• CLK-IN Input
• Single-channel PWM current control stepper motor driver
(selectable with DC motor driver channel 2) incorporated.
• BiCDMOS process IC
• Excitation step proceeds only by step signal input
• IO max = 1.5A
