CXAS42270在1.5V到5.5V的输入电压下工作,适用于1.8V、3V和5V系统。输入逻辑电平与TTL和2.5V至5V CMOS兼容。典型的静态电源电流为4μA。在关机模式下,电源电流减小到小于1μA。CXAS42270采用6针TDFN 1.6X1.6mm封装。CXAS42270是一个单P通道MOSFET电源开关,专为高压侧负载切换应用而设计。MOSFET在VCC=5V时具有典型的80mΩRDS(ON),允许在低正向电压降下增加负载开关电流处理能力。CXAS42270有一个回转率限制接通负载开关,并提供一个连接到OUT的停机负载放电引脚,以便在开关禁用时快速断开负载电路。
1.5V至5.5V输入电压范围
·非常低的RDS(开),通常为80mΩ(5V)
·回转率限制开启时间1毫秒(5伏)
