LV8731V

Ordering number : ENA1482B LV8731V Monolithic Linear IC PWM Constant-Current Control Stepper Motor Driver http://onsemi.com Overview The LV8731V is a 2-channel H-bridge driver IC that can switch a stepper motor driver, which supports micro-step drive with 1/16-step resolution, 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. Function Single-channel PWM current control stepper motor driver (selectable with DC motor driver channel 2) incorporated. BiCDMOS process IC Low on resistance (upper side : 0.3Ω ; lower side : 0.25Ω ; total of upper and lower : 0.55Ω ; Ta = 25°C, IO = 2A) Micro-step mode can be set to Full-step, Half-step, Quarter-step , or 1/16-step Excitation step proceeds only by step signal input Motor current selectable in four steps Output short-circuit protec...
