General Description
The G526 is an integrated dual channel 100mΩ 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.
OC is open-drain output report over-current or
over-temperature event and has typical 9ms deglitch
timeout period.
