G547E1P81U datasheet pdf Power Distribution Switch

The G547E1 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. G547E, G547F, G547G,G547H and G547M are 90mΩ R DS(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.
