Features

• • The Over Voltage Protection (OVP) monitors VX, V33, V5, V12A and V12B input voltage.
    
  • The Under Voltage Protection (UVP) monitors V33, V5, V12A and V12B input voltage.
    
  • The Over Current Protection (OCP) monitors I33&33, I5&V5, I12A&V12A and I12B&V12B input pins.
    
  • 2.9V Under Voltage Protection for V33 (*T0) (*T2) (*T4)
    
  • 2.2V Under Voltage Protection for V33 (*T1) (*T3)
    
  • 3.8V Over Voltage Protection for V33 (*T0) (*T2) (*T4)
    
  • 3.9V Over Voltage Protection for V33 (*T1) (*T3)
    
  • The VX > 1.2V provide an extra protection.
    
  • Both of the power good output (PGO) and fault protection latch (FPOB) are Open Drain Outputs.
    
  • 75/600 ms time delay for UVP / OCP / VX.
    
  • 125 ms time delay for PGO when PGI>1.2V and V33/V5/V12A/V12B are all above the under voltage thresholds.
