General Description
The  G527  is  a  current  limited  N-channel  MOSFET  power  switch  designed  for  highside  load  switching  applications.   The    low    RDS(ON) N-channel    power    MOSFET  is  driven  by  a  built-in  charge  pump  which  generates  a  voltage  higher  than  the  supply  voltage  to  fully enhance the switch.

This  switch  operates  with  inputs  ranging  from  2.7V  to  5.5V,  making  it  ideal  for  both  3.3V  and  5V  sys-tems.  An  integrated  current-limiting  circuit  protects  the  input  supply  against  large  current  which  may  cause the supply to fall out of regulation. The G527 is also protected from thermal overload which limits power  dissipation  and  junction  temperatures.  Cur-rent  limit  threshold  is  programmed  with  a  resistor  from  SET  to  ground.  When  the  output  voltage  is  higher   than   input   voltage,   the   power   switch   is   turned  off  by  internal  output  reverse-voltage  com-parator.

An  open-drain  flag  output  is  also  available  to  indi-cate  fault  condition,  including  overcurrent,  thermal  shutdown,  and  output  reverse-voltage  condition.  In  shutdown  mode,  the  supply  current  decreases  to  less  than  1μA.  The  reverse  leakage  current  is  also  less than 1μA.

The  G527  is  available  in  SOT-23-6,  TSOT-23-6,  MSOP-8 and MSOP-8 (FD) packages.
