Hi Lukasz,
BQ24780S is the improved version. They are pin-to-pin compatible devices.
I would recommend BQ24780S. It is also a public part so you will find lot better support on it.
Thanks and I hope this helps,
Peng

I am looking for much more technical explanation as I'm the design engineer. What I found so far is that 780 does not have a Fast DPM feature which 780s does have, the System Power Monitor feature is a V-mode in 780 while an I-mode in 780s, and also the charging current limiter in 780 is set by either ILIM or Register while in 780s there is only a Register-based charging current limiter. The above questions the full compatibilty between these two devices, although they are - in fact - pin2pin compatible. Are there any other differences between them?

Please refer to the comparison table by my colleague.
For future support related to BQ24780, please go to your local TI FAE first.
Thanks,
