DESCRIPTION
SG6513 is designed to provide the voltage, current
and temperature supervisor function, remote on/off
(PSON) function, power good (PGO) indicator function,
and fault protection (FPO) function for switching power
systems.
For supervisor function, it provides the over voltage
protection (OVP) monitoring for 3.3V, 5V and 12V; over
current (OCP) monitoring for 3.3V, 5V and 12V; under
voltage sense (UVS) monitoring for 3.3V, 5V and 12V;
under voltage protection (UVP) monitoring for 12V; and
over temperature protection (OTP) for SG6513T. When
3.3V, 5V or 12V voltage is decreasing to 2.8V, 4.2V and
9.9V respectively, the under voltage sense (UVS)
function will be enabled to reset the PGO signal from high
to low. If 12V voltage is further decreasing to 9V, FPO
will be set to high to turn off the PWM controller IC. The
voltage difference across external current shunt is used for
OCP functions. An external resistor can be used to adjust
protection threshold. To achieve better immunity for
lighting surge glitch and to prevent accidental power shut
down during dynamic loading condition, the de-bounce
time for UVP/OCP and UVS is 275us/125us ,350us
respectively. The deglitch time for OVP is 75uS for better
noise immunity.
The power supply is turned on after 38mS de-bounce
time when PSON signal is set from high to low. To turn
off power supply, PSON signal is set from low to high and
the de-bounce time is 115mS. The PGI circuitry provides
a sufficient power-down warning signal for PGO. When
PGI input is lower than the internal 1.2V reference
voltage, after 250uS de-bounce time, the PGO signal is
pulled low.

Description
Power good input. For ATX SMPS, it detects AC line voltage through the main transformer.
Ground.
Fault protection output. Output signal to control the primary PWM IC through a
opto-coupler. When FPO is low, the main SMPS is operational.
Remote On/Off logic input from CPU or main-board. The power supply will be turned on/off
after 38mS / 115mS delay.
12V over current protection sense input. Regarding typical application, this pin is
connected to the positive end of a current shunt through one resistor. When the voltage on
IS12 is higher than that of VS12 by 5mV, OCP will be enabled. One current sink, 8 x Iref, is
used to determine the voltage drop between the positive end of the current shunt and
VS12. Adjusting the value of the external resistor can adjust the threshold for OCP
accordingly. The operation for IS5 or IS33 is the same.
Reference setting. One external resistor Ri connected between RI and GND pin will
determine a reference current, Iref = 1.15/Ri, for OTP and OCP programming.
Over-temperature protection. Only valid for SG6513T.
An NTC thermistor is connected from RT pin to GND. At high temperature, the impedance
of the NTC will decrease and hence the voltage on RT will decrease. When the voltage on
RT pin is lower than 0.95V limit, the over-temperature protection will be enabled. The
internal pull high current source is equal to 5 x Iref.
5V over current protection sense input.
3.3V over current protection sense input.
12V over/under-voltage control sense input.
3.3V over/under-voltage control sense input.
