Description

SG6510 is designed to provide the voltage supervisor

function, remote on/off PSON function, power-good

(PGO) indicator function, and fault protection (FPO)

function for switching power systems.

For the supervisor function, it provides the over-voltage

protection (OVP) monitoring for 3.3V, 5V, and 12V (12V

via VDD pin); under-voltage sense (UVS) monitoring for

3.3V and 5V; and under-voltage protection (UVP)

monitoring for 3.3V and 5V. When 3.3V or 5V voltage is

decreasing to 2.8V and 4.2V, respectively, the under-

voltage sense (UVS) function is enabled to reset the

PGO signal from high to low. If 3.3V or 5V voltage is

further decreasing to 2.5V and 3.6V, respectively, FPO

is set high to turn off the PWM controller IC. To achieve

better immunity for lighting surge glitch and to prevent

accidental power shut down during dynamic loading

condition, the debounce time for UVP and UVS is

2ms/1ms, respectively. The deglitch time for OVP is

75µs for better noise immunity. During an AC sag or

brownout situation, UVP functions can still be enabled

to protect power supply in case of output short circuit.

The power supply is turned on after 38ms debounce

time when the PSON signal is set from high to low. To

turn off the power supply, the PSON signal is set from

low to high and the debounce time is 38ms. The PGI

circuitry provides a sufficient power-down warning

signal for PGO. When PGI input is lower than the

internal 1.2V reference voltage, after 350μs debounce

time, the PGO signal is pulled low.
