Abstract
An electronic circuit that recognizes a disconnected state from an outside during disconnection of a power supply line is provided. For this purpose, an electronic circuit includes: a load provided between a power supply line and an output terminal in the electronic circuit; a transistor provided between the load and the output terminal; a current generation circuit that generates current using a power supply voltage at a power supply line in the electronic circuit; and a control circuit that controls the transistor using a control voltage that changes according to the current generated by the current generation circuit.
