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 RDS(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.
