GMT G524D1T11U Integrated Power Switch

General DescriptionThe G524 is an integrated power switch forself-powered and bus-powered Universal Serial Bus(USB) applications. G524A, G524B, G524C, G524Dare 70mΩ RDS(ON).Several Protection features include current limiting andthermal shutdown to prevent catastrophic switch failurecaused by increasing power dissipation when continuousheavy loads or short circuit occurs. A built-incharge pump is used to drive the N-channel MOSFETthat is free of parasitic body diode to eliminate anyreversed current flow across the switch when it is poweredoff. When the output voltage is higher than inputvoltage, the power switch is turned off by internal outputreverse-voltage comparator.OC is an open-drain output report over-current orover-temperature event and has typical 9ms deglitchtimeout period. In addition, OC also reports outputreverse-voltage condition with typical 5ms deglitchtimeout period.
