Ordering Information
Description
The SG6520A is designed to provide the supply
voltage, current supervisor, remote on/off (PSON),
power good (PGO) indicator, and fault protection (FPO)
functions for switching power systems.
For supervisory functions, 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 decreases to 2.3V,
3.5V, and 9V, respectively, the under-voltage protection
function is enabled. FPO is set HIGH to turn off the
PWM controller IC. The voltage difference across the
external current shunt is used for OCP functions. An
external resistor can be used to adjust protection
threshold. An additional protection input pin provides
the flexibility for designing protection circuits.
The power supply is turned on after a 48ms delay 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 a delay of 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.
