产品简介

CXUS7726 CXUS7726A CXUS7726B是一个具有限流功能和输出OVP保护的功率分配开关，可以提供高达0.1A的电流。该装置包括一个250mW N沟道MOSFET功率开关。该装置集成了限流保护、输出过电压保护、过温保护和UVLO保护等功能。电流限制保护可以通过在过载或短路事件期间将输出电流限制在电流限制阈值来防止下游设备发生灾难性故障。当VOUT存在异常高电压时，输出过电压保护可防止电流从VOUT流向VIN。过温保护功能在结温超过140oC时关闭N沟道MOSFET电源开关，在温度下降20oC时自动打开电源开关。UVLO功能保持电源开关处于关闭状态，直到存在有效的输入电压。该设备提供无铅SOT-23-3和SOT-23-5封装。

   产品概述 返回TOP

The CXUS7726/A/B is a power-distribution switch with current- limiting function and output OVP protections that can deliver current up to 0.1A. The device incorporates a 250mW N-channel MOSFET power switch. The device integrates some protection features, including current-limit protection, output over-voltage protection, over-temperature protection and UVLO. The current-limit protection can protect down-stream devices from catastrophic failure by limiting the output current at currentlimit threshold during over-load or short-circuit events. The output over-voltage protection can prevent current flowing from VOUT to VIN when an abnormally high voltage exists in VOUT. The over-temperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 140o C and will automatically turns on the power switch when the temperature drops by 20o C. The UVLO function keeps the power switch in off state until there is a valid input voltage present. The device is available in lead free SOT-23-3 and SOT-23-5 packages.
