High Current Power Switch

DESCRIPTION

The  SP69  is  a  low  Rds(on) high  current  switch  designed  with  precision  current  limiting  to  protect  connected  devices  from  damage  due  to  a  short  circuit  condition  or against  current  surges  that  may  cause  the  supply  voltages  to  fall  out  of  regulation.  This  switch  operates  from  an  input  voltage  range  of  2.5V  to  7V, making  it  ideal for  3V  and  5V  applications.   The  SP69  is  also  protected  from  thermal  overload which  limits  power  dissipation.   In  shutdown  mode,  the  supply  current  drops  to  2µA.
