SG6510X1
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.

Wide supply voltage range from 4V to 15V
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.
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 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

Fault protection output (invert). Output signal to control the PWM IC. For example it
controls the PWM IC of primary side through an opto-coupler. When FPO is low, the
main SMPS is operational.
