I've been using the bq20z65-R1 for quite some while as an in-system 3-cell LiPo protector - I am now however looking at adding an on-board charger to my design.
After reading http://focus.ti.com.cn/cn/lit/an/slua533/slua533.pdf it seems that this can be done without a host (i.e. microcontroller) - [much simpler!] :)
Question:
Is the BQ24747 charger suitable to be used with the bq20z65-R1 in this "no-host" configuration?
If so, are there any critical design issues I should be aware of?
As a side question (for a diff design): Could the BQ28400 (2-cell gas gauge) be used with the BQ24747 charger in the same "no-host" config?
Thanks in advance to anyone who can help me answer these questions :)
