Abstract
A magnetic sensor integrated circuit, a motor assembly and an application device are provided. The integrated circuit includes a housing, a semiconductor substrate, at least one input port and an output port, and an electronic circuit arranged on the semiconductor substrate. The electronic circuit includes a rectifying circuit, a magnetic field detection circuit configured to detect an external magnetic field and output magnetic field detection information, and an output control circuit connected to the rectifying circuit, and configured to control, at least based on the magnetic field detection information, the integrated circuit to operate in at least one of a first state in which a load current flows from the output port to an outside of the integrated circuit and a second state in which a load current flows from the outside of the integrated circuit to the output port. The load current flows through the rectifying circuit.
