... SILICON TOUCH TECHNOLOGY INC. PS232S 6-Channel Secondary Monitoring IC General Description PS232S is specially designed for switching power supply system. Four important functions of PS232S 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 quartic 12V to protect our power supply and PC, FPO/ goes to high when one of these supply voltages exceeds their normal operation voltage range ...
