PS25A - 3-Channel Secondary Monitoring IC

General 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.

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 3-Channel Seconda.

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.
