Hi,
May I understand if output of BQ24090 is tristate when not charging? There is an option to add alkaline battery and no blocking diode is added.
If blocking diode is added, then the BQ24090 has to be higher than 4.2V to charge.
Can also comment if the below implementation post any issue with BQ24090?
By the way, the Li-ion battery is 2400mAh.
Thanks,
Christina
