GMT G517D2T11U SOT-23-5

　　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 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

　　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.
