摘要：A power supply control signal generating circuit includes a connector, a switch, atransistor, and an input-output (I/O) controller. The connector includes a first pin and agrounded second pin. The switch has two terminals respectively coupled to the first pin

and the second pin of the connector. The transistor has its base coupled to the first pinof the connector and a power supply via a first resistor, its collector coupled to thepower supply via a second resistor, and its emitter grounded. The I/O controller has aninput terminal coupled to the collector of the transistor, and outputs a power supplycontrol signal at the output terminal.
