General Description
The G524 is an integrated power switch for
self-powered and bus-powered Universal Serial Bus
(USB) applications. G524A, G524B, G524C, G524D
are 70mΩ RDS(ON).
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.
OC is an open-drain output report over-current or
over-temperature event and has typical 9ms deglitch
timeout period. In addition, OC (G524X3/4, X=A, B,
C, D) also reports output reverse-voltage condition
with typical 5ms deglitch timeout period
