　　General Description

　　The G547 is an integrated power switch for

　　self-powered and bus-powered Universal Serial Bus

　　(USB) applications. G547E, G547F, G547G,G547H

　　and G547M are 90mΩ RDS(ON).

　　Several Protection features include current limiting with

　　foldback, 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.

　　OC is open-drain output report over-current or

　　over-temperature event and has typical 9ms deglitch

　　timeout period.
