Dual Power Distribution Switch CXAS42280 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

   产品概述 返回TOPHew嘉泰姆

The CXAS42280 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.
