FEATURES OVERVIEW
DESCRIPTION
and temperature supervisor function, remote on/off
(PSON) function, power good (PGO) indicator function,
and fault protection (FPO) function for switching power
systems.
TYPICAL APPLICATION

Version 1.0PN ( IRO33.0014.B0)
Over-voltage protection (OVP) for 3.3V, 5V and
12V
Over-current protection (OCP) for 3.3V, 5V and 12V
Under-voltage sense (UVS) for 3.3V, 5V and 12V
Under-voltage protection (UVP) for 12V
Open drain output for PGO and FPO pins
300mS power good delay
75mS delay for 3.3V, 5V and 12V power turn on
2.8mS PSON control to FPO turn-off delay
38mS / 115mS PSON control De-bounce
275uS width noise deglitches
De-bounce time 125uS for UVP and OCP
De-bounce time 350uS for UVS
No lockup during the fast AC power on/off
Brownout protection function for 12V
Wide supply voltage range from 4V to 15V

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.
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.

... 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 ...
