.DataSheet.co.kr Ordering number : ENA1824A LV8734V Overview Bi-CMOS LSI PWM Constant-Current Control Stepping Motor Driver The LV8734V is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step drive and supports 2W 1-2 phase 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 stepping motors used in office equipment and amusement applications. Features - Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated. - BiCDMOS process IC - Low on resistance (upper side : 0.48Ω ; lower side : 0.32Ω ; total of upper and lower : 0.8Ω ; Ta = 25°C, IO = 1.5A) - Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 2W1-2 phase - Excitation step proceeds only by step signal input - 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 - Built-in thermal shutdown circuit - No control power supply...
