ABSTRACT:
A space-saving back-up power supply apparatus has length and width dimensions substantially the same as those of a conventional integrated circuit connector. The apparatus includes sockets arranged on its top for making connection to a socket-pluggable integrated circuit such as a standard CMOS RAM, and the apparatus has pins extending from its bottom for making connection to a printed circuit board or connector of a host electronic system. Control circuitry and one or more batteries are located within the apparatus. The back-up power supply is operative to provide power to the socket-pluggable integrated circuit even if the normal power supply of the host electronic system is short-circuited. The control circuitry of the back-up power supply controls the chip enable signal and performs a battery test upon power-up.
