LV8741V Bi-CMOS IC www.onsemi.com PWM Current Control Stepper Motor Driver 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 SSOP44K (275mil) Single-channel PWM current control stepper motor driver (selectable 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 = 25C, I = 1.5A) O 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 I max = 1.5A O 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 V = 2.7V to 5.5V CC 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 ORDERING INFORMATION See detailed ordering and shipping information on page 28 of this data sheet.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details. Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, damage may occur and reliability may be affected.
