2021年2月2日——东芝电子元件及存储装置株式会社（“东芝”）今日宣布，推出新型eFuse IC“<a href="https://toshiba-semicon-storage.com/cn/semiconductor/product/power-mana… lang="EN-US">”，进一步丰富了eFuse IC产品线。该产品可重复使用，具有保护电源线电路的功能。

玻璃管熔断器和贴片熔断器等传统物理熔断器在过流状态下物理切断电源线，以起到保护电源线的作用，但一旦熔断就必须更换。eFuse IC旨在替代此类熔断器，为电源线提供保护和安全性，同时在高度精确的过流保护之外，提供一系列内置的保护功能。

TCKE712BNL采用过压保护功能保护电源线，该功能可根据用户要求通过外部电阻器进行调整。同时，它内置关断状态下的反向阻断电流功能，可用于电源多路复用器应用。此外，它还内置有过流保护、短路保护和热关断功能。该器件还具有FLAG功能，如果电路中发生异常，可以发出外部信号，与东芝当前的产品相比，更容易检测到可能的故障。

东芝将继续强化eFuse IC产品线，以保护多种用途的电源线。

应用：

电源线的电路保护

（笔记本电脑、游戏控制器、增强现实和虚拟现实设备、智能音箱、扫地机器人、网络服务器等）

特性：

关断状态下的反向阻断电流功能

用户定义的可调节过流／过压保护功能

FLAG信号输出功能

纤薄紧凑的WSON10封装：3.00mm×3.00mm（典型值），厚度＝0.75mm（最大值）

主要规格：

（除非另有说明，@Ta＝25℃）<o:p></o:p>
