摘要：
An auto-clear circuit which has a switch device connected between a power supply voltage terminal and first and second nodes, and a potential division device, connected between the first node and a ground terminal, for outputting a first potential obtained by dividing a potential of the first node. Also included is a charge/discharge device, connected between the second node and a ground terminal, for charging or discharging the second node on the basis of the first potential output from the potential division device, and a latch device for holding a potential of the second node to output a signal from an output terminal, and supplying the signal to the switch device to control an opening/closing operation.
