nPM2100 - usage with nRF9151?

[Achim Kraus]

According the nPM2100 page "nPM2100 comes with exceptional software support for Nordic’s nRF52, nRF53, and nRF54 Series" but doesn't mention "nRF91 Series". 

Currently I miss support for solar charger from Nordic. Adding a solar+usb charger available from other manufacturers, would then a nPM2100 fit also for the nRF91?

It will not work with batteries less than 3.6V (because they need to be connected directly to the nRF91) and the 150mA must meet to other consumers, but are there any other limitation of the nPM2100, which prevents to use it for the nRF91?

Hi Achim

nPM2100 PMIC is not intended to be used with rechargeable batteries.

It is not a fit for nRF91 Series products.
nPM2100 PMIC is a boost regulator aim for non-rechargeable batteries. 
1.8 V to 3.3 V output voltage with 150 mA Output current maximum.
0.8 V to 3.0 V in LDO mode with 50 mA Output current maximum.

Also, currently we don't have any PMIC in our portofolio which can support energy harvesting.

I don't want to use the nPM2100 as charger, just as power regulator for VDD_GPIO. For the nPM2100 a combination of an solar charger and rechargeable battery (both other manufacturers) is pretty much the same as non-rechargeable batteries, which (hopefully) never gets drained.
