UNISONIC TECHNOLOGIES CO., LTD 3513
PC POWER SUPPLY SUPERVISOR
CMOS IC
DESCRIPTION
The UTC 3513 is designed to provide protection circuits, power
DIP-16
good output (PGO) indicator, fault protection output (FPOB) and a
PSONB control for PC switching power supply systems.
The protection circuits include over voltage protection (OVP), under
voltage protection (UVP) and over current protection(OCP) monitoring
for 3.3V, 5V and two 12V.
When 3.3V, 5V or 12V voltage is decreasing to 2.68V, 4.3V and 9.9V respectively, the under voltage protection (UVP) function will be
SOP-16
enabled. FPO will be set to high to turn off the PWM controller IC.
Toggling the PSONB from low to high will reset the fault protection
latch.
