Other Parts Discussed in Thread: BQ24650
Our customer is developing an irrigation controller. The system is powered by a 12V 5Ah Lead Acid battery and a solar panel. He was searching for a battery charger with MPPT feature and NVDC architecture. He found out about BQ25798 but was wondering if it is suitable for charging the lead acid battery.
If yes, what type of configuration does he need to select? 4S? Does he need to make other changes to charge the lead acid battery?
Since this charger is not available at the moment, is there any charger with similar characteristics that can fit his system needs?
What I can see is that BQ25798 is suitable for charging only Li-Ion/Li-Polymer, Lithium Phosphate/LiFePO4. For the mentioned requirements, I have filtered our product list while considering MPPT feature, NVDC architecture and suitability for charging lead acid battery as shown in the link below:
But then, I received feedback from our customer: "The problem with these ICs that you selected for me is that the description tells that they support solar input/MPPT but in the datasheet, there is nothing about it. So the descriptions are wrong. They do not support the MPPT algorithm. Is it still efficient to connect a solar panel to these charger? Thanks"
I hope you can help us. Thank you.
