APW1681JC-TU-3 Channel Power Monitor
The APW1681 is a power supply system designed to minimize external PC swapping components. It provides protection circuit, power good indicator, fault protected output FPO and PSON control. OVP (Over Voltage Protection) monitors 3.3V, 5 V, and 12 V (12 V OV is detected through the V CC terminal). UVP (under voltage protection) monitors 3.3V and 5V. When an OV or UV condition is detected, the "police routine" (power good output) is set low and FPOis latched high. PSON is reset from low to high to protect the latch. There is a 2.36ms turn-off delay fromPSON toFPO. There is no delay on the transfer process. The power good function monitors the PGI, 3.3V and 5V voltages and issues, a power good signal when they are ready.
