Is there any chipset to balance 4x12 (48V) litium batteries?

Hi Roberto,

We don't currently offer a automotive chipset for monitoring 12V cells since we are targeting applications for Li-ion cells ~4V range.

If you mean 4V per cell with 12 in series Li-ion then you may be interested in bq75614-Q1 which is targeted for 48V applications: https://www.ti.com/product/BQ75614-Q1 . Currently the device is not yet fully released but scheduled to release very shortly. You can read the short datasheet to get main idea of the feature set.

Best Regards,

Taylor

Thanks Taylor

I was searching in TI something like LTC3305 (Linear Tech - 12V Lead-Acid Batteries) for 12V Litium Batteries.

We've been working with BQ76PL536A for a BMS cell array.

Best regards

Roberto

Hi Roberto,

Apologies, we currently don't offer a device like this.
