Abstract:
The present invention relates to a method and a circuit for power switching. The method comprises the steps of: providing a operation circuit; receiving a command from a Host and setting up a power mode of the operation circuit; supplying a first rated consuming power source and then a second rated consuming power source to the operation circuit via the power switching circuit according to power mode; detecting the transferring process form the first rated consuming power source to second rated consuming power source; and preventing over current according to detecting result.
