PS224 - 4-Channel Secondary Monitoring IC

General Description

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.

Key Features

  • Over/Under-voltage protection and lock out Over-current protection and lock out Additional protection input Fault protection output with open drain output stage Open drain power good output signal for power good input Built-in 300mS power good delay AC on 75ms delay for UV/OC protection 38mS PSON/ control de-bounce Wide power supply range (3.8V~16V) Special care for AC power off 4-Channel Seconda.

PS224 PS224 4-Channel Secondary Monitoring IC General Description 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.
