Abstract
A magnetic sensor integrated circuit, a motor and an application apparatus are provided. The magnetic sensor integrated circuit includes an input port, a magnetic sensor, and a signal processing unit. The input port is electrically coupled to an external power source. The magnetic sensor senses a polarity of an external magnetic field and outputting a detection signal. The signal processing unit includes a switched capacitor filter unit to sample and filter the detection signal; the signal processing unit eliminating an offset of the detection signal.
