75mS turn on delay for 3.3V and 5V
2.8mS PSON control to FPO turn-off delay
38mS /38mS PSON control De-bounce
350uS width noise deglitches
2mS UVP De-bounce time
1mS UVS De-bounce time

Wide supply voltage range from 4V to 15V
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.
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 will be 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
will be set to 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 de-bounce time for UVP and UVS
is 2mS/1mS respectively. The deglitch time for OVP is
75uS for better noise immunity. During AC sag or
brownout situation, the UVP functions still can be enabled
to protect power supply in case of output short circuit.
The power supply is turned on after 38mS de-bounce
time when PSON signal is set from high to low. To turn
off power supply, PSON signal is set from low to high and
the de-bounce 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 350uS de-bounce time, the PGO signal is
pulled low.
For supervisor function, it provides the over voltage
protection (OVP) monitoring for 3.3V, 5V and 12V (12V

Type Description
Fault protection output (invert). Output signal to control the PWM IC. For example it
controls the PW M IC of primary side through an opto-coupler. When FPO is low, the
main SMPS is operational.
Remote On/Off logic input from CPU or main-board. Turn on/off the PW M output after
38mS / 38mS delay.
Supply voltage. 4V ~ 15V. For AT X SMPS, it is c onnected to 5V-standby and 12V through
diodes respectively.
Power good logic output, 0 or 1(open-drain). P ower good=1 means that the power is
good for operation. The power good delay is 300mS.
