CXAS42269是一个N通道MOSFET功率开关，专为高压侧负载开关应用而设计，该装置的典型RDS（ON）为85mΩ，输出电流限制在2A，CXAS42269具有一个转换率限制的接通负载开关，并提供一个关闭负载放电电路，在开关被禁用时快速关闭负载电路。CXAS42269在2.0V到5.5V的输入电压范围内工作。它适用于3V和5V系统。CXAS42269还具有欠压锁定功能，当存在输入欠压情况时，该功能将关闭开关。输入逻辑电平与TTL和2.5V至5V CMOS兼容。在关机模式下，电源电流减小到小于1μA。
2.0V至5.5V输入电压范围
·非常低的RDS（开），通常为85mΩ（5V）
·VCC=5V时，典型电流限制为2.5A
·回转率限制开启时间1.5毫秒（5伏）
