目录7.相关产品 产品概述 返回TOP The CXUS7722A CXUS7722B is a power-distribution switch with some protection functions that can deliver current up to 2A. The device incorporates a 90mW 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-1.5V 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 140oC and will automatically turns on the power switch when the temperature drops by 20oC. 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-23-5, TDFN2x2- 6 and SOP-8 packages with enable active-high(EN) and active-low(ENB) versions.产品特点 返回TOP · 90mW High Side MOSFET · 2A Continuous Current · Soft-Start Time Programmable by External Capacitor · Wide Supply Voltage Range: 2.7V to 5.5V · Current-Limit and Short-Circuit Protections · Under-Voltage Lockout Protection · Reverse Current Blocking when Switch Disabled · Over-Temperature Protection · Logic Level Enable Input CXUS7722A: Active High ACXUS7722: Active Low · Lead Free and Green Devices Available (RoHS Compliant) 应用范围 返回TOP · TFT LCD Modules · Notebook and Desktop Computers · USB Ports · High-Side Power Protection Switches 技术规格书(产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们,还可以获得免费样品以及技术支持!
