G529	2.7	5.5	70	1.00	1.1	Y	N	Fast SCP, HML 2.0 VOUT Reverse-Current Protection	SOT-23-6

 

General Description
The   G529   is   an   integrated   power   switch   for   self-powered and bus-powered Universal Serial Bus (USB) applications. RDS(ON) is 70mΩ.

Several Protection features include current limiting and thermal  shutdown  to  prevent  catastrophic  switch  fail-ure caused by increasing power dissipation when con-tinuous  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  eliminate  any  reversed current flow across the switch when it is pow-ered off. When the output voltage is higher than input voltage, the power switch is turned off by internal out-put reverse-voltage comparator.

OCis   open-drain   output   report   over-current   or   over-temperature  event  and  has  typical  9ms  deglitch  timeout  period.  In  addition,  OC  also  reports  output  reverse-voltage  condition  with  typical  5ms  deglitch  timeout period.
