General Description
The G517 is an integrated power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications.
Several Protection features include current limiting 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. When the output voltage is higher than
input voltage, the power switch is turned off by internal
output reverse-voltage comparator.
FLAG is an open-drain output report over-current or
over-temperature event and has typical 9ms deglitch
timeout period.
