eFuse ICs

當電流超過額定值時,傳統的保險絲會通過焦耳熱將內置的合金部件融合在一起,從而保護電路並防止設備損壞。然而,這些熔斷器具有諸如斷路電流不確定,熔斷時間慢以及由於單個過電流破壞而需要更換工作的缺點。與傳統的保險絲不同,eFuse IC(electronic fuse)具有高速電流中斷功能,因為當過大的電流流過時,內置的MOSFET會關閉。此外,它不會被單個過電流破壞,並且可以重複使用。其優點在於它可以結合各種保護功能,例如過壓保護。該產品還可以有效減少維護成本並縮短維修時間。

PCB photo example of Power multiplexer circuit
Power Multiplexer Circuit Using Common-Drain MOSFET
This power multiplexer circuit with 2 inputs and 1 output is realized on a small board. A new power multiplexer circuit usign common-drain MOSFET has been added to the already developed power multiplexer circuit reference design. These reference circuits allow switching between BBM and MBB modes by combining optimal devices such as MOSFET gate driver ICs and zener diodes from our diverse product lineup.
