G524B1T11U datasheet pdf Single Power Switch

The G524 is an integrated power switch for self-powered and bus-powered Universal Serial Bus (USB) applications. G524A, G524B, G524C, G524D are 70mΩ R DS(ON) .

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.

OC is an open-drain output report over-current or over-temperature event and has typical 9ms deglitch timeout period. In addition, OC also reports output reverse-voltage condition with typical 5ms deglitch timeout period
