Tool/software:

Hi,

I am looking for a battery charger solution that meets the following requirements:

3 Li-ion 18650 batteries
Charging voltage: 24V
No CPU dependency
Low cost

I intend to use the BQ76942 for its management, and the charger must be capable of working together with it.

If possible, I would like to know if there is any application note about integrating a charger and management ICs in the same circuit.

Thank you.

Hello Lucas,

Here is a list of all of our battery chargers:https://www.ti.com/battery-management/charger-ics/products.html

Most of the battery chargers we have that will go up to 24V charge voltage are standalone, so I don't know if they will work with the BQ76942. I recommend posting a new question related to the BQ76942.

We also have BQ25756/BQ25756E/BQ25750 these are controlled through I2C.
