G547E

Global Mixed-mode Technology G547E/F/G/H/M 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. Power Distribution Switch Features 90mΩ High-Side MOSFET (G547E,G547F,G547G,G547H, G547M) Available with 5 Versions of Current Limits with Foldback Operating Range:2.7V to 5.5V 1mS Typical Rise Time Fast Overcurrent Response -3µs (TYPICAL) Under voltage Lockout 100µA Quiescent Supply Current 1µA Maximum Shutdown Supply Current Logic Level Enable Pin, Available with Active-High or Active-Low Version No Reverse Current when Power Off Deglitched Open-Drain Over-Current Flag Output ( OC ) With Output Shutdown Pull-low Resister SOT-23-6, SOP-8, MSOP-8 and TDFN3X3-8 Packages UL Approved_#E232223 Nemko IEC 60950-1 CB/CCA_scheme Certification Report #67291 OC is open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period.
