ABSTRACT:
A power-down circuit includes a power-on reset circuit that determines whether the supplied power falls below a prescribed level and, in response, outputs a reset signal for at least a prescribed period of time. A power supply latching circuit is responsive to the power-on reset circuit for switching on a power supply switching circuit to supply power from a power supply when the reset signal is not output. A power-down shutdown circuit, preferably under software control, and a power cutoff circuit, may be coupled to the power supply latching circuit, or alternatively the power-on reset circuit, for shutting down the power supplied from the power supply.
