CXAS42260高级负载管理交换机针对需要高度集成的解决方案的应用程序。如果用严格的关断状态电流目标和高负载电容（高达200μF）断开直流电源轨（<6V）供电的负载。每个开关由转换率控制的低阻抗MOSFET开关（23mΩ型）和其他集成模拟特性组成。回转率控制的导通特性可防止浪涌电流和由此导致的电源轨上的过大电压降。CXAS42260具有TRCB功能，在开/关状态下阻止从VOUT到VIN的不需要的反向电流。这些器件具有非常低的关断状态电流漏（最大<2μA），这有助于在非常低的待机功率应用中实现合规性。输入电压范围从1.5V到5.5V DC，以支持用户的广泛应用。光学、医疗存储、便携式和工业设备电源管理。开关控制由一个逻辑输入（有源高电平）进行管理，该逻辑输入能够直接与低压控制信号/GPIO接口，无需特别的下拉电阻器。该设备采用WLCSP2X3-6针封装。

产品概述 返回TOP
The CXAS42260 advanced load-management switches target applications requiring a highly integrated solution. If disconnects loads powered from DC power rail (<6V) with stringent off-state current targets and high load capacitances (up to 200μF). Each switch consists of slew-rate controlled low-impedance MOSFET switch (23mΩ type) and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. The CXAS42260 has TRCB function blocking unwanted reverse current from VOUT to VIN during ON/OFF state. These device have exceptionally low off state current drain (<2μA max) which facilitate compliance in very low stand by power applications. The input voltage range operates from 1.5V to 5.5V DC to support a wide range of applications in consumer. Optical, medical storage, portable and industrial device power management. Switch control is managed by a logic input (Active HIGH) capable of interfacing directly with low voltage control signal/GPIO with no extremely pull-down resistor required. The device is packaged in WLCSP2X3 -6 pin.
