MAGNETIC SENSOR INTEGRATED CIRCUIT, MOTOR COMPONENT AND APPLICATION APPARATUS

摘要

A magnetic sensor integrated circuit, a motor assembly and an application device are provided. The magnetic sensor integrated circuit includes a magnetic field detection circuit and an output control circuit. The magnetic field detection circuit is configured to detect a magnetic field of a rotor of a motor and output magnetic field detection information. The output control circuit includes a first switch and a second switch. The first switch and the output port are connected in a first current path. The second switch and the output port are connected in a second current path having a direction opposite to that of the first current path. The first switch and the second switch are selectively turned on based on the magnetic field detection information, so as to control an energizing mode of the motor.
