Abstract
A power supply switching circuit includes a switching circuit that electrically connects a VCC terminal and a VBK terminal in a connected state, a switch control circuit, and a power supply monitoring circuit that monitors a voltage of the VCC terminal, and outputs a voltage of the VBK terminal. The switch control circuit switches a mode from a normal mode in which the switching circuit is intermittently connected to a standby mode in which the switching circuit is opened according to an output signal of the power supply monitoring circuit.
