APW1681
3-Channel Power Supply Supervisor
Features
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.
Over Voltage Protection and Lock Out for
! 3.3 V, 5 V, and 12 V

! Output Stage
•
!
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
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.
