Abstract
The invention relates to an electronic device comprising at least two power management circuits and a signal line connecting the circuits. Each of the circuits is adapted to control a power supply to at least one functional component of the electronic device. Each of the circuits is adapted to detect a condition which requires powering down functional components of said electronic device and to set the signal line to a predetermined state, in case the circuit detects a condition which requires a powering down of the electronic device. Further, each of the circuits is adapted to monitor a state of the signal line and to power down all functional components associated to it upon detection of the predetermined state of the signal line.
