Overview
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.
Feature
 Single-channel PWM current control stepper motor driver (selectable
SSOP44K (275mil)
with DC motor driver channel 2) incorporated.
 BiCDMOS process IC
 On resistance (upper side : 0.5 ; lower side : 0.5 ; total of upper and
lower : 1.0 ; Ta = 25C, IO = 1.5A)
 Excitation mode can be set to Full-step, Half-step full torque, Half-step or Quarter-step
 Excitation step proceeds only by step signal input
 Motor current selectable in four steps
 IO max = 1.5A
 Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated
 Thermal shutdown circuit and power supply monitor circuit incorporated
 Support control power supply VCC = 2.7V to 5.5V
Typical Applications
 Stepper/Brush DC Motors
 Computing & Peripherals, Industrial
 Printers, Inkjet Printer, Multi-Function Printer
 Flatbed Scanner, Document Scanner
 Slot Machine, Vending Machine, Cash Machine
