I do have the datasheet but maybe this one is more up to date somehow. Will have to check. > > Btw I'm working on AXP15060 support mostly based on your series. Lovely to hear. So sorry for the very very late reply. New semester began 3 weeks ago and been quite the ride. Would love to get the series more up to date in the upcoming weeks :) I will see what time allows :) > > > Best regards, > > Shengyu Best regards,
