产品说明
The LV8774Q is a 2-channel H-bridge driver IC, and can drive a stepper motor or two brushed DC motors. A stepper motor driver supports micro-step drive with 1/16-step resolution, and two brushed motor drivers support forward, reverse, brake, and standby functions. It is ideally suited for driving brushed DC motors and stepper motors used in office equipment and amusement applications.
