MP2797 : Auto Balancing

Hi MPS Team,

I’m using the MP2797 and I would like to know if the following configuration is correct to enable autobalancing at charge and also in Standby mode?
The behavior that I’m looking for is a kinf of “infinite” balancing until reaching the MSM threshlod for all the cells.
By advance thank you for your help.

Kind regards,
Arnaud

Hi Arnaud,
Allow me to confirm and I will follow up with you,
The two that you have enabled is correct.

This AFE device has passive balancing, I want to ensure its not confused with active balancing.
In passive balancing, you bleed charge, therefore net charge decreases for the pack, while helping charge the respective low cell/s.

Best,
Nouman

Hi Nouman,

Thank you for your feedback.
I guess I have solved my issue by changing the configuration a little bit.
Te be able to perform auto balancing on charge and in standby mode, I changed the parameter “Use repetition” to “Use list”. After testing, it seems to work properly now.

Kind regards,
Arnaud
