电子保险丝/熔断器(eFuse IC)

当电流超过额定值时,传统的保险丝将通过焦耳热熔化内置合金部件来保护电路和防止设备损坏。然而,这些保险丝的缺点是:分断电流不确定,熔断时间慢,以及由于单个过电流破坏而需要进行更换。与传统保险丝不同,eFuse IC具有高速电流中断功能,因为当电流过大时,内置MOSFET会关闭。此外,它不会被单一过电流破坏,可重复使用。它的优点在于它可以结合各种保护功能,比如过电压保护。该产品还可以有效地降低维护成本和维修恢复时间。

参考设计

多路复用器电路PCB照片示例
使用共漏极MOSFET的电源多路复用器电路
此参考设计中,在一个小型印刷电路板(PCB)上实现了具有2个输入和1个输出的电源多路复用器电路。我们现已在已开发的电源多路复用器电路参考设计中增加了使用共漏极MOSFET的应用电路。这些参考电路通过组合东芝多种产品线中的MOSFET栅极驱动IC和齐纳二极管等最佳器件,可以实现BBM和MBB模式的切换。
