Three important functions of PS113A are the following: over-voltage protection, short circuit protection and power good signal generating. OVP (Over Voltage Protection) monitors 5V, 12V and 3.3V to protect our power supply and PC, when one of these supply voltages exceeds their normal operation voltage. Short circuit protection is done by UVP (Under Voltage Protection). When power supply is in short circuit, the supply voltages will be much smaller than their normal operation voltages .We can use UVP to monitor our power supply whether it is in the dangerous power load. Power good signal generating notifies personal computer when power supply is ready or power supply is going to shutdown, therefore it can provide a reliable power supply environment. Features Over voltage protection and lock out Short circuit protection and lock out Fault protection output with open drain output stage Open drain power good output signal for power good input Built-in 300ms power good delay 75ms delay for short-circuit turn on protection 38ms PSON control de-bounce 20us de-bounce for noise immunity Wide power supply range from 4V to 16V Pin to pin compatible with TPS3510 Special care for AC power off Additional 12V UVP protection 3-Channel Secondary Monitoring IC -1Version：A.003 PS113A Block Diagram FPO/ Vcc R1 VCCI 20uS De-bounce 12 UV SQ R 1MΩ R2 Vref VCCI delay 12 OV H : 4mS L : 4.5uS VCCI R3 Vref VCC 10uA VS5 R4 VCCI 38mS De-bounce PSON/ Vref 4.5V 2KΩ 5 UV R5 Vref VCCI 5 OV R6 Vref delay H : 75mS L : 4.5uS 1 0 VCCI 1.13V VCCI VS33 R7 VCCI PGI 0.63V R QS VCCI 3.3 UV R8 Vref VCCI 1.25V 3.3 OV R9 Vref 1MΩ VCCI PGO delay 73uS De-bounce H : 300mS L : 4.5uS Vref 1.25V Power On Reset POR Internal Power VCCI = 4V Band-Gap Reference Clock Generator CLK GND 3-Channel Secondary Monitoring IC -2- Version：A.003 PS113A Timing Chart Vcc PSON/ FPO/ PGI VS12 VS5 VS33 PGO Td1 Td2 AC turn on UVP/OVP protect Tb1 Td3 PSON/ turn on PSON/ turn off PSON/ turn on AC turn off VPGI 1.25V 1.13V 0.63V Td1 Td2 OVP OVP/UVP OVP 3-Channel Secondary Monitoring IC -3- Version：A.003 PS113A Pin Descriptions Pin No 1 2 3 4 5 6 7 8 PIN NAME PGI GND FPO PSON VS33 VS5 VCC PGO Ground Inverted fault protection output ,open drain output stage ON/OFF control input pin 3.3V over/under voltage protection input pin 5.0V over/under voltage protection input pin Supply voltage/12V over voltage protection input pin Power good output signal pin , open drain output stage Descriptions Power good input signal pin Absolute Maximum Ratings Parameter Storage Temperature Supply Voltage Input Voltage Range (Tstg) (VCC) (VI) VCC VS33,VS5 PGI PSON/ Output Voltage Range ESD Susceptibility* (VO) (VESD) FPO/ PGO -40 -30 -0.5 -0.5 -0.5 -0.5 -0.5 -0.5 Operating Temperature (Topr) Rating to to to to to to to to > +125 +90 +16.0 Vcc+0.5 Vcc+0.5 Vcc+0.5 Vcc+0.5 Vcc+0.5 2500 Unit °C °C V V V V V V V * Human Body Model (HBM).
