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 R

DS(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 elimi­nate 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.

Applications

 High-Side Power Protection Switch
 USB Power Management
 USB Host and Self-Powered Bubs
 USB Bus-Powered Hubs
 Hot Plug-In Power Supplies
