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.
