Part Number: BQ25798
Other Parts Discussed in Thread: BQ25790,

Hi expert,

We are promoting BQ25798 to replace BQ25790 in INSTA360 and keep TI's share. Customer want TI to provide the spec and test comparison between BQ25790 and BQ25798. I can't find any comparison in Seismic. Could you help to provide some detailed comparison? Thanks.

Best Regards,

Ryker
