Hot selling spot PS224 DIP-16 4-Channel Secondary Monitoring IC

Product Descriptions

PS224 is specially designed for switching power supply system. Four important functions of PS224 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 dual 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 protection input pin provides the flexibility for design protection circuit.

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.
