    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.

    An  adjustable  over-current  condition  composed  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  computer  when  power  supply  is  ready  or  power  supply  is  going  to  shutdown,  therefore  it  can  provide  a  reliable  power  supply environment.
