ABSTRACT:
An circuit arrangement acts in response to an external wake signal to provide fail-safe, battery saving control to a power supply. The arrangement includes a power supply, a microcomputer which is responsive to the external wake signal for providing a shutdown indication to indicate when the power supply should be disabled, and a power supply controller which is responsive to the external wake signal and to the shutdown indication for controlling the inactivation of the power supply. The controller validates the shutdown indication by comparing it to the status of the wake signal so as to provide fall-safe power supply control.
