power-good (PGO) indicator function, and fault
protection (FPO) function for switching power systems.
For supervisor, it provides 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 decreases to 2.3V, 3.5V, and 9V respectively,
the under-voltage protection (UVP) function is enabled.
FPO is 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 a 48ms delay time
when PSON signal is set from high to low. To turn off the
power supply, the 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, the PGO
signal is pulled low.
