产品简介

CXUS7735 CXUS7735A是一个配电开关，具有一些保护功能，可提供高达2.5A的电流。该设备包括一个78mW N通道MOSFET电源开关，该开关由一个使能逻辑引脚控制，并具有一个专用于软启动加速率控制的SS引脚，可用于涌流为该装置集成了限流保护、短路保护、超温保护和UVLO保护等功能。电流限制和短路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。当电压降到低于VIN-1V时，设备会将电流限制在一个较低且安全的水平。过温保护功能在结温超过150℃时关闭N沟道MOSFET电源开关，当温度下降20℃时自动打开电源开关。UVLO功能将电源开关保持在关闭状态，直到存在有效的输入电压。

   产品概述 返回TOP

The CXUS7735  CXUS7735A is a power-distribution switch with some protection functions that can deliver current up to 2.5A. The device incorporates a 78mW N-channel MOSFET power switch that is controlled by an enable logic pin and has a SS pin dedicated to soft start ramp-up rate control that can be used in application where the inrush current is concerned.The device integrates some protection features, including current limit protection, short circuit protection, overtemperature protection and UVLO. The current limit and short circuit protection can protect down-stream devices from catastrophic failure by limiting the output current at current limit threshold during over-load or short circuit events. When VOUT drops below VIN -1V the devices limit the current to a lower and safe level. The over-temperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 150 oC and will automatically turns on the power switch when the temperature drops by 20 oC. The UVLO function keeps the power switch in off state until there is a valid input voltage present.
