ABSTRACT:
A circuit is provided for detecting out of range or specification voltages of a power supply output and for disabling the power supply in response thereto. Disabling of the power supply is effected in time delay fashion and a signal is generated to indicate impending disabling of the power supply. The signal may be used to trigger dumping of logic circuit information to registers pending shutdown of the power supply.
