ELPW5208-1.2A Dual USB Power Loading Switch

General description

The ELPW5208 is an integrated 130mΩ power switch for self-powered   and   bus-powered   Universal   Series   Bus (USB)  applications.  A  built-in  charge  pump  is  used  to drive  the  N-Channel  MOSFET  that  is  free  of  parasitic body diode to eliminate any reversed current flow across the   switch   when   it   is   powered   off.   Its   low   quiescent current      (16μA)       and small package (SOT23-5) is particularly suitable in battery-powered       portable

equipment. Several  protection  functions  include  soft  start  to  limit inrush current during plug-in, current    limiting at 1.2A to meet     USB power requirement, and thermal  shutdown  to  protect  damage  under  over  current conditions.
