We are looking for charge management IC for 2S1P Li- polymer battery.
The charger IC should support following
Input voltage : 8-36V,
Battery capacity: 6600mAh
Fuction: It can effectively switch the power from main input(8-36V) to battery when the main power supply is unavailable.
It could be helpful if you suggest the suitable battery charger IC with the above spec.

Hi, Thanks for your reply.
I hope the previously suggested ICs are all buck converter charger ICs. However, our battery charge cutoff voltage is 8.4V. If we provide a minimum input voltage of 8V, these ICs won’t function effectively to charge the battery, as they are buck converters.

Could you please suggest any buck boost battery charger IC?

Hello again,

Thanks for adding the extra information. Here are some Buck-Boost charger ICs that I can recommend, however the input voltages don’t go all the way up to 36V Vin like the buck chargers I have recommended before:

These ICs are public on the website, but MPS is always working on more ICs every year. If these don’t fit the bill, please submit a ticket for more chargers in the works: Contact MPS - Contact
