台湾致新 G524B2T11U SOT-23-5 代理商主推

　　General Description

　　The G524 is an integrated power switch for

　　self-powered and bus-powered Universal Serial Bus

　　(USB) applications. G524A, G524B, G524C, G524D

　　are 70mΩ RDS(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.

　　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
