ABSTRACT:
This power detection circuit is comprised of a power-down detection circuit for detecting the first detection level and a power-on detection circuit having the second detection level higher than the first detection level, and the power detection circuit compulsorily initializes a power-on latch circuit by the output signal lowlevelx of the power-down detection circuit and also initializes the power-down detection circuit and the power-on detection circuit by the switch of a starter circuit.
