G526 Global Mixed-mode Technology Inc. Dual Power Distribution Switch Features General Description The G526 is an integrated dual channel 100mΩ power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. 100mΩ High-Side MOSFET Operating Range:2.7V to 5.5V 400µS Typical Rise Time Under voltage Lockout 65µA 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 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. Output ( OC ) SOP-8 Package UL Approved_#E232223 OC is open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period.
