Abstract
An electronic device comprising a first power switch connectable or connected between a first voltage source and a load is proposed. The first power switch assumes a conductive state in response to a power-on request and a non-conductive state in response to a power-off request, for energizing and deenergizing the load, so that a voltage across the first power switch tends to a positive high level when the first power switch is in the non-conductive state and to a positive low level when the first power switch is in the conductive state. The device further comprises a second power switch connectable or connected between a second voltage source and the load. The second power switch assumes a conductive state in response to the power-on request and a non-conductive state when the voltage across the first power switch is below a defined switch-off threshold lower than the high level. The second voltage source thus assists the first voltage source in powering up the load. A method of operating the electronic device is also described.
