SG6510D1

Product Specification PC Power Supply Supervisors 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. 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 ATX SMPS, it detects main AC voltage under-voltage and/or failure. Ground. 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. Remote On/Off logic input from CPU or main-board. Turn on/off the PWM output after 38mS / 38mS delay. 3.3 V over/under-voltage control sense input. 5 V over/under-voltage control sense input. Supply voltage. 4V ~ 15V. For ATX SMPS, it is connected to 5V-standby and 12V through diodes respectively. Power good logic output, 0 or 1(open-drain). Power good=1 means that the power is good for operation. The power good delay is 300mS. 4 5 6 7 8 PSON VS33 VS5 VDD PGO Logic input Analog input Analog input Supply Logic output © System General Corp.
