General Description
The G5250 is an integrated 85mΩ power switch for self-powered and bus-powered Universal Serial Bus (USB) applications.
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. And 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.
G5250E/F/G/H, G5250I/J/K/L and G5250M/N/P has open- drain
over-temperature event and has typical 9ms deglitch timeout period.
