Product Specification
PC Power Supply Supervisors
SG6516
power-good (PGO) indicator function, and fault
protection (FPO) function for switching power systems.
FEATURES
Two 12V sense input pins: VS12 and VS12B
Over-Voltage Protection (OVP) for 3.3V, 5V,
and two 12V
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.
Over-Current Protection (OCP) for 3.3V, 5V,
and two 12V
Under-Voltage Protection (UVP) for 3.3V, 5V,
and two 12V
Open-drain output for PGO and FPO pins
300ms power-good delay
300ms turn-on delay for 3.3V, 5V, and two 12V
2.8ms PSON control to FPO turn-off delay
48ms PSON control delay
No lockup during the fast AC power on/off
Wide supply voltage range from 4V to 15V
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.
DESCRIPTION
SG6516 is designed to provide the voltage and current
supervisor function, remote on/off (PSON) function,

APPLICATION NOTE
Over-Current Protection (OCP)
very small offset voltage ( 5mV). The sink currents of
IS33, IS5, and IS12 are eight times the current at the RI
pin. The current at the RI pin is VRI/RI. Below is an
example demonstrating how to set OCP.
The SG6516 provides over-current protection for the
3.3V, 5V, and two 12V rails. Whenever an OCP
condition occurs at any of the voltage rails, PGO is low
and FPO is open. The internal OCP comparators have a
If:
I1 • R1>(IRI • 8) • R2, then
OCP active.
(1)
To select an R2 resistor:
If
R1=5mΩ, RI=30K, and
OCP protection level is 35A, then
R2 = (I1 • R1) / (IRI • 8)
= (35A • 5mΩ) / {(1.25V/30K) • 8}
= 525Ω
