Product Summary

The PS223 is a 4-Channel Secondary Monitoring IC. PS223 is specially designed for switching power supply system. Four important functions of PS223 are the followings: over-voltage protection, over-current protection, under-voltage protection and power good signal generating. OVP/UVP (Over-Voltage/Under-Voltage Protection) monitors 3.3V, 5V and double 12V to protect our power supply and PC, FPO/ goes to high when one of these supply voltages exceeds their normal operation voltage range. OCP(Over Current Protection) monitors IS33, IS5, IS12A, IS12B input current sense. An adjustable over-current condition composed of Iref and “protection current range resistor” helps users design OCP easily. An additional OTP channel helps users monitor if there have any over temperature occur. 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.
