BQ24195L Charging while keeping PMID outputing

S L61

Other Parts Discussed in Thread: BQ24195L, BQ24140

I am using BQ24195L.

I can set REG01[5:4] = 10/11 as OTG so that PMID can be an output but what should I do if I want to charge my battery at the same time?

You cannot output the 5V OTG on PMID and charge at the same time. The IC either chargers the battery uses its buck converter or operates the buck converter in reverse as a boost converter, with the battery as the input to the boost converter and the 5V OTG supply as the output.

The bq24140 will charge and output 5V OTG at the same time.
