   产品概述 返回TOPPcb嘉泰姆

The CXAS42220 is an integrated 95mΩ (TYP) power switch for self-powered and bus-powered Universal Series Bus (USB) applications. 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. Low quiescent supply current and small package are particularly suitable in battery-powered portable equipment.Pcb嘉泰姆

Several protection functions include soft-start to limit inrush current during plug-in, current limiting at 1.85A to meet USB power requirement, and thermal shutdown to prevent damage under over current conditions.Pcb嘉泰姆

The CXAS42220 is available in a Green SOT-23-5 package and is rated over the -40℃</span> to +85℃</span> temperature range.Pcb嘉泰姆
