    Abstract: A magnetic sensor integrated circuit includes an electronic circuit arranged on a semiconductor substrate, and input ports and first and second output ports extending out from a housing. The electronic circuit includes a magnetic field detection circuit and an output control circuit. The magnetic field detection circuit is configured to detect an external magnetic field and generate magnetic field detection information. The first output port outputs the magnetic field detection information to an outside of the housing. The output control circuit is configured to control, based at least on the magnetic field detection information, the integrated circuit to operate in at least one of a first state in which a current flows from the second output port to an outside of the integrated circuit and a second state in which a current flows from the outside of the integrated circuit to the second output port.
