POWER MANAGEMENT IN A CIRCUIT

摘要

The present disclosure is generally related to power management in a circuit on a circuit board of a processor. The circuit includes a first power connector coupled to a first power input rail. The circuit includes a second power connector and a second power input rail. The circuit includes a control module. The control module is configured to determine a power specification of the circuit board. The control module is configured to detect a power cable connected to the first control connector. The control module is configured to sense a voltage at the second power connector. The control module is configured to couple the second power input rail with the first power connector or the second power connector in response to the determined power specification of the circuit board and the sensed voltage at the second power connector.
