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 Output ( OC ) „ SOP-8 Package Applications „ High-Side Power Protection Switch „ USB Power Management „ USB Host and Self-Powered Bubs „ USB Bus-Powered Hubs „ Hot Plug-In Power Supplies „ Battery-Charger Circuits General Description The G556 is an integrated dual channel 100mΩ 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.
OC is open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period.
