General Description 

The  G547  is  an  integrated  power  switch  for self-powered and bus-powered Universal Serial Bus (USB)  applications.  G547E,  G547F,  G547G,G547H and G547M are 90mΩ RDS(ON). Several Protection features include current limiting with foldback, and thermal shutdown to prevent catastrophic switch  failure  caused  by  increasing  power  dissipation when continuous heavy loads or short circuit occurs. A built-in  charge  pump  is  used  to  drive  the  N-channel MOSFET that  is  free of  parasitic  body  diode  to  elimi-nate any reversed current flow across the switch when it is powered off.


OC is  open-drain  output  report  over-current  or over-temperature  event  and  has  typical  9ms  deglitch timeout period.
