Part Number: TPL5111
As I know without battery charging IC, how to use nano power timer IC - TPL5111.
in my circuit I have placed nano power timer IC after battery charger IC - but in that case the intension to use nano power such as 30nA will not be fulfilled as battery charger IC (BQ25611D) consuming 9.5uA QUIECENT current - which is very larger than 30nA.
Can I put green highlighted circle block - before the battery charging IC ? in that case I have only one confusion - that when I will plug the charger , will my current be flown from gate/load switch's vout to vin and will charge my battery ? can I use load switch in that case or I have to use MOSFET as a switch ? can any expert please help ?
We are looking into your question and will reply by 5/26

Thanks for sharing the information. You could place the circled block before the battery charging IC, but this means that the battery charging circuit may be power-cycled, meaning you would need to reinitialize the battery charger every time it restarts.
I can help you with TPL5111 questions, but I'm not an expert on the other devices. For support with BQ25611 or the load switch, please submit a new post to the appropriate forum. It seems you need a load switch with reverse current protection
