CXUS7730A CXUS7730B是一个具有一些保护功能的配电开关，可以提供高达2A的电流。该设备包括一个由使能逻辑控制的90mW N沟道MOSFET功率开关。该装置集成了一些保护功能，包括限流保护、短路保护、超温保护和UVLO。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VOUT低于1.5V时，设备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功能将电源开关保持在关闭状态，直到存在有效的输入电压。设备有无铅SOT-23-5封装，支持高电平（EN）和低电平（ENB）版本

产品概述 返回TOP
The CXUS7730A/B 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. 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 packages with enable active-high(EN) and active-low(ENB) versions
