Question How to use only 1.8V line on RVL-PMS

[Gi0V1Z]

Hi, I’ve recently fried my RVL-PMS by inserting the cell backwards
I was wondering, since the component visibly fried is the U7, can I still use the 1.8V converter instead of the LDO?
I’ve found on the forum were is the 1.8V converter, but I’m not into PCBs, so I don’t get were and what voltage to put.

Thanks in advance

If just the BQ is fried, why not just replace that? You can probably get one off Aliexpress or see if anyone around here has a spare. Better than trying to cannibalize the rest of the PMS.

Hi, I’ve followed your advice and bought a spare of the BQ (link).
I think that’s the same part…

1) Could the pinout be different?
2) It’s just a replacement or do I need some programming step in order to get everything working?
