General Description

The APW1681 is designed to minimize the external components of personal-computer switching power supply systems. It provides protection circuits, power good indicator, fault protection output FPO    and PSON  control. OVP (over voltage protection) monitors 3.3V, 5 V, and 12 V (12 V OV detects via V CC terminal). UVP (under voltage protection) monitors 3.3V and 5V.
When an OV or UV condition is detected, the PGO (power good output) is set to low and FPO  is latched to high. PSON  from low to high resets the protection latch. There is a 2.36ms turn-off delay fromPSON   to FPO  . There is no delay during turn on.
Power good feature monitors PGI, 3.3V and 5V under voltages, and issues a power good signal when they are ready.
