SG6520 is designed to provide the voltage, and current
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) for 3.3V, 5V and two 12V; over current
protection (OCP) for 3.3V, 5V and two 12V; under
voltage protection (UVP) for 3.3V, 5V and two 12V.
When 3.3V, 5V or 12V voltage is decreasing to 2.3V,
3.5V and 9V respectively, the under voltage protection
(UVP) function will be enabled. 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.
The power supply is turned on after 48mS delay time
when PSON signal is set from high to low. To turn off
power supply, PSON signal is set from low to high with
the delay time 48mS. The PGI circuitry provides a
power-down warning signal for PGO. When PGI input is
lower than the internal 1.25V reference voltage, PGO
signal is pulled low.
