Abstract
A sensor integrated circuit includes a rectifier, a power supply module, an output control circuit and a detecting circuit. The rectifier is configured to convert an external power supply into a first direct current power supply. The power supply module includes a voltage regulator configured to generate a second direct current power supply different from the first direct current power supply. The detecting circuit is powered by the second direct current power supply and configured to detect an inputted signal and correspondingly generate a control signal. The output control circuit is configured to control, in response to at least the control signal, the sensor integrated circuit to operate in at least one of a first state in which a current flows out from an output port and a second state in which a current flows in from the output port.
