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 fail-
ure caused by increasing power dissipation when con-
tinuous 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 pow-
ered off. When the output voltage is higher than input
voltage, the power switch is turned off by internal out-
put 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 also reports output
reverse-voltage condition with typical 5ms deglitch
timeout period.

*: 1µF of input capacitor is enough in most application cases.
If the PCB trace of power rail to IN is long, larger input capacitor is necessary.
