Abstract
A magnetic sensor integrated circuit and a motor component are provided. The integrated circuit includes a housing, a semiconductor substrate arranged inside the housing, input ports and an output port which extend out from the housing, and an electronic circuit arranged on the semiconductor substrate. The electronic circuit includes a magnetic field detection circuit configured to detect and output a magnetic field inductive signal corresponding to an external magnetic field, and a voltage detection circuit configured to detect a specific voltage and output, in a case that the specific voltage reaches a predetermined value, a control signal for controlling the magnetic sensor integrated circuit to perform a preset action. The voltage detection circuit and the magnetic field detection circuit operate simultaneously.
