| APW1683 3-Channel Power Supply Supervisor Features Over Voltage Protection and Lock Out for ! 3.3 V, 5 V, and 12 V General Description The APW1683 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 2.3ms turn-off delay from PSON 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. * * !
