SG6516

PC Power Supply Supervisors

Features

Description

The SG6516 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.

Two 12V Sense Input Pins: VS12 and VS12B

Over-Voltage Protection (OVP) for 3.3V, 5V,

and two 12V

Over-Current Protection (OCP) for 3.3V, 5V,

and two 12V

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

external current shunt is used for OCP functions. An

external resistor can be used to adjust the protection

threshold. An additional protection input pin provides

the flexibility for designing protection circuits.

Under-Voltage Protection (UVP) for 3.3V, 5V,

and two 12V

Open-Drain Output for PGO and FPO Pins

300ms Power-Good Delay

2.8ms PSON Control to FPO Turn-off Delay

48ms PSON Control Delay

No Lock-up During the Fast AC Power On/Off

Wide Supply Voltage Range: 4V to 15V

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.
