Abstract
The external power supply comprises a modem, a power source for providing an operating voltage for the modem and a supply voltage for an appliance and a power safe control. The power safe control comprises a current sense element for sensing a supply current of the supply voltage and a threshold circuit coupled to the current sense element for switching off the operating voltage when the supply current is below a threshold value, and for switching on the operating voltage when the supply current is above the threshold value. The appliance is in a preferred embodiment a residential gateway or a set-top box and the modem a power line communication modem.
