    產(chǎn)品信息

    The LV8740V 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 DC 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.
    • On resistance (upper side : 0.3Ω ; lower side : 0.2Ω ; total of upper and lower : 0.5Ω ; Ta = 25°C, IO = 2.5A)
    • Excitation mode can be set to Full-step, Half-step full torque, Half-step , or Quarter-step
    • Motor holding current selectable in four steps
    • Output short-circuit protection circuit (selectable from latch-type or auto reset-type) incorporated
    • Built-in thermal shutdown circuit
    • No control power supply required
    • 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
    • Unusual condition warning output pins
    • Forward/Reverse/Brake/Stand-by Function
