Apple MacBook A2442 faulty PMIC - Question about possible replacement

[arahban]

Hello Gentlemen,

I am working on an apple MacBook A2442 board pn 820-02098-A with a visible short on the PMIC U7700 MVK-PLUS as per the schematics

I have a donner board from apple macbook pro m1 A2338 PN 820-02020 and I saw that the PMIC U8100 TMLT46B0-JPE could be a possible replacement for the U7700

Can you please help me confirm if the U7700 can be replaced with U8100 ?

APL1098 is it the same as APL1096

Thank you very much in advanced

Ahmad

Do note that the PMIC likely blew from a shorted/cracked ceramic capacitor, so make sure you trace the actual short and find the culprit once you remove PMIC.

You can replace PMIC from that board and you should get most functions. I cannot confirm if there will be ZERO problems, but we have swapped those two PMICs (specifically 02016-->02098) and it worked. We have also done 02016-->02020, and it worked. So, I would presume 02020-->02098 will work fine as well. However, it's best-practice to always source programmed ICs from identical models. In this case it may be OK; try it!
