Kind Code:
A1
Abstract:
Provided is an electronic circuit that can recognize, from the outside, a disconnection state when a power supply line is disconnected. To this end, the electronic circuit has: a load that is provided between an output terminal and a power supply line in the electronic circuit; a transistor that is provided between the load and the output terminal; a current generation circuit that generates a current using a power supply voltage of the power supply line in the electronic circuit; and a control circuit that controls the transistor using a control voltage that varies according to the current generated by the current generation circuit.
