Hi Kevin,

Yes.. eFuse can be used to replace PTC function and it provides additional values discussed in the following blog

https://e2e.ti.com/blogs_/b/powerhouse/archive/2015/09/15/get-out-of-the-dark-upgrade-your-fuse

I recommend TPS2662 eFuse as replacement for 2920L185DR PTC and TPS2595 as replacement for 0805L035YR PTC. Let us know if you have any further questions.

Best Regards, Rakesh
