Hi

How can 87D detect OCP when using external HV path?

It looks 87D don't have sense pins.

    Hello Anderson,

    You are correct in that the TPS65987D does not offer over current protection for the external power paths. If you lookin within the datasheet and go to section 8.3.3.3 PP_EXT Power Path Control, it explains this feature as well as that OCP and thermal protection are not supported for the external power path.

    The TPS65987D incorporates this feature for both of the internal power paths.

    Hope this helps answer your question!
