ABSTRACT:
A power-low reset circuit is provided. The power-low reset circuit receives a reset signal outputted from a power on reset circuit and a stored voltage of a capacitive device in the power-on reset circuit provides an electrical path when a power voltage drops under a predetermined voltage level. The power-on reset circuit is used for generating the reset signal at an initial moment of turning on a power source. The capacitive device can be discharged or charged through the electrical path to restore to its initial status.
