CXLS4264E是具有超低导通电阻P-MOSFET的高压侧开关。集成限流功能，可对升沉电容性负载、过负载电流、短路电流进行限流，保护电源。
CXLS4264E还集成了反向保护功能，可在设备关闭时消除通过开关的任何反向电流。当设备关闭时，输出自动放电使输出电压迅速下降。热关机功能可以保护设备和负载。

一.产品概述
The CXLS4264E is high-side switch with ultra-low ON resistance P-MOSFET. Integrated current-limit function can limit inrush current for heave capacitive load, over load current, and short-circuit current to protect power source.
The CXLS4264E is also integrated reverse protection function to eliminate any reverse current flow across the switch when the device is off. Output auto-discharge while the device shutdown made output voltage off quickly. Thermal shutdown function can protect the device and load.
The CXLS4264E is available in SOT-23-5L package. Standard product is Pb-free and Halogen-free.
