G529 Global Mixed-mode Technology Power Switch for MHL Features General Description 70mΩ High-Side MOSFET Current Limit for MHL Power Switch Operating Range:2.7V to 5.5V 1mS Typical Rise Time Fast Overcurrent Response -3µs (TYPICAL) Under voltage Lockout 130µA 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 The G529 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. RDS(ON) is 70mΩ. Several Protection features include current limiting 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. When the output voltage is higher than input voltage, the power switch is turned off by internal output reverse-voltage comparator. Output ( OC ) Output Reverse-Voltage Protection SOT-23-6 Packages OC is open-drain output report over-current or over-temperature event and has typical 9ms deglitch Applications timeout period. In addition, OC also reports output reverse-voltage condition with typical 5ms deglitch timeout period.
