PC POWER SUPPLY
SUPERVISORS
DESCRIPTION
The UTC
3510
is designed to provide protection circuits, power
good output (PGO) indicator, fault protection output (FPO) and a
PSON control for PC switching power supply systems.
The protection circuits include over voltage protection (OVP)
monitoring for 3.3V, 5V and 12V (12V via V
DD
pin) and under voltage
protection(UVP) monitoring for 3.3V and 5V. When an OV or UV event
arose and is detected, the power good output (PGO) goes low and the
FPO will be set to high. The protection latch can be reset by setting
PSON to high. UVP function is enabled 75ms after PSON is set low
and de-bounced. Besides, there is a 2.3ms delay with 38ms
de-bounce at turn off but no delay during turn on.
When OVP and UVP detected the right voltage level, a PGO signal
will be issued.
