PC POWER SUPPLY
SUPERVISOR
DESCRIPTION
The UTC 3513 is designed to provide protection circuits,
power 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 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.
The voltage difference across external current shunt is used
for OCP functions. An external resistor can be used to adjust
protection threshold.
* Pb-free plating product number: 3513EL/3513FL
The power supply is turned on after 38mS delay time when
PSONB signal is set from high to low. To turn off power
supply, PSONB signal is set from low to high with the delay
time 38mS. The PGI circuitry provides a power-down warning
signal for PGO. When PGI input is lower than the internal
1.20V reference voltage, PGO signal is pulled low.
The device is available in two versions: UTC 3513E/3513F.
Specially, fan control function is available in OTP/FC pin of
UTC 3513F.
FEATURES
* OVP/UVP monitors 3.3V, 5V, 12V input voltage level.
* OCP monitors IS33, IS5, IS12 input current sense.
* Fault protection output (FPOB) with Open Drain Output
stage.
* Power good output (PGO) with Open Drain Output stage.
* 38ms de-bounce time for PSONB input signal.
* 300ms time delay from PGI to PGO.
* 2.4ms time delay for PSONB to turn off FPOB.

Fault Protection Output. Output signal to control the primary PWM IC
through an opto-coupler. When FPOB is low, the PWM IC is enabled.
Remote On/Off logic input from CPU or main-board. The power
supply will be turned on/off after 38mS delay.
Over temperature protection/Fan speed control
Reference setting. One external resistor Ri connected between RI
and GND pin will determine a reference current, IREF = 1.20/Ri, for
OCP programming.
