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
