General Description
The G5250 is an integrated 85mΩ power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications.
Several Protection features include current limiting
with foldback, and thermal shutdown to prevent catas-
trophic switch failure caused by increasing power dis-
sipation when continuous heavy loads or short circuit
occurs. And 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.
G5250E/F/G/H and G5250I/J/K/L has open-drain
OC output reports over-current or over-temperature
event and has typical 9ms deglitch timeout period.
