PS25A
Description PS25A is specially designed for switching power supply system. Four important functions of PS25A 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 triple 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 IS12A, IS12B, IS12C input current sense. An adjustable over-current condition posed 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 puter when power supply is ready or power supply is going to shutdown, therefore it can provide a reliable power supply environment. Features - Over/Under-voltage protection and lock out - Over-current protection and...
