BQ77180x family 3-terminal fuse

David Wang11

In the datasheet of the BQ77180x family of parts, it shows that the 3-terminal fuse is attached to the pack+ signal line. The only manufacturer that can be found that suits this is Dexerials "self control protector". Are there any other manufacturers you would know that have similar parts suitable for this part?

Another manufacturer of chemical fuses is Schott, and this is the link to their product: http://www.us.schott.com/epackaging/english/cutoff/sh_type/d6.html

There might be others but I can't think of any others that make chemical fuses like these.

Hope this helps!

Sony does make chemical fuses too such as the sfh 1212A. They are hard to obtain though and most people avoid using them altogether.

Dexerials used to be called Sony Chemicals; the product names are still the same. I was able to obtain 30 SFH-1212A chemical fuses for development/testing a while back from an online parts broker, but needless to say it was an ordeal trying to get them.
