Part Number: BQ25895

Hi,

I was Actually going through the E2E portal on on Battery management IC BQ25895 IC, I found that in one of the thread it was mentioned "The system voltage may drop slightly resulting in Reset to the System Load connected", Is that true, Actually I have the same requirement of Powering a Raspberry Pi Using Solar Power.

Hi Ning,

Here is the Link https://e2e.ti.com/support/power-management/f/196/p/513572/2023078?tisearch=e2e-quicksearch&keymatch=bq25895+Raspberry%20pi#2023078

Please go through the reply by Steven as follows

"The bq25895 can in fact provide 5V at PMID while charging the battery (assuming input is 5V), the problem here is that when you disconnect the adapter and turn on OTG, the transition will have a small drop, which could reset your system. I suggest looking at the solution in the first paragraph."
