The power supply is turned on after a 48ms delay time when PSON signal is set from high to low. To turn off the power supply, the PSON signal is set from low to high with the delay time 48ms. The PGI circuitry provides a power-down warning signal for PGO. When PGI input is lower than the internal 1.25V reference voltage, the PGO signal is pulled low.
