PS113 3-Channel Secondary Monitoring IC
General Description
PS113 is specially designed for switching power supply system. Three important functions of PS113 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 73us 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
