General Description

PS224B is specially designed for switching power supply system.

Four important functions of PS224B 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.

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.
