FAN7685/FAN7686/FAN7687  
PC Power Supply Output Monitoring IC  
Features  
Description  
• PC Power Supply Outputs Supervisory Circuitry  
• Few External Components  
The FAN7685/FAN7686/FAN7687 is a complete output  
supervisory circuitry intended for use in the secondary side  
of the switched mode power supply. It provides overvoltage  
protection (OVP), undervoltage protection(UVP), overcur-  
rent protection (OCP), and power good signal generator to  
monitor and control the outputs of the switching power sup-  
ply system. Remote on/off(PSON) control and some preci-  
sion protection features are also implemented.  
• Over Voltage Protection for 3.3V, 5V and 12V Outputs  
• Under Voltage Protection for 3.3V, 5V and 12V Outputs  
• Over Current Protection for 3.3V, 5V and 12V Outputs  
• Dual Over Current Portection for 12V Outputs(FAN7687)  
• Fault Protection Output With Open Drain Output  
• Open Drain Power Good Output  
• 300ms Power Good Delay  
• 38ms PSON On/Off Delay  
• 73us Debounce  
• 2.3ms PSON to FPO Turn Off Delay  
• Latch Function Controlled by PSON  
It directly senses all the output rails for OVP, UVP, and OCP  
without external divider resistors. As for output control,  
power good output(PGO) and fault protection output(FPO)  
are included. The FAN7685/FAN7686/FAN7687 offers a  
simple and cost effective solution with minimum number of  
external components and greatly reduces PCB board space  
for power supply.
