Hello,

In the BQ76920 datasheet a Companion Controller IC BQ783xx is mentioned.

I cannot find this product family (BQ783xx) in the catalogue.

Please provide a link to the aforementioned device.

Thanks!

Hi George,

Good eye! The companion controller IC, bq78350, is in fact wrapping up development right now and we plan to release this in 3Q this year.

Regards,

Allen

Hallo Allen,

is there any news on the release date of the bq78350?

If you have a moment to spare, I also would like to ask if there are any other possible microcontroller which can regulate the cell balancing of the bq76940, besides the aforementioned bq78350.

Thank you for your time.

Hi Lotfi,

Glad you asked! We are in final prep for releasing the bq78350 and expect it to go live on TI.com next week.

The product page is here: http://www.ti.com/product/bq78350

As for your MCU question, the bq78350 is the main product that is specifically designed to work with the bq76940 family. It's also possible to pair many conventional MCU's (such as an MSP430) to work with the bq76940 ICs, but requires that the customer develop their own firmware for those micros.

Regards,

Allen

Hi Allen,

I have ordered a bq76940 and it is currently being shipped to me.

If I have understood correctly, the bq76940 comes with a bq78350 already equipped. Is this correct? If not, I will order it extra. Also I would like to know in the case of a power outage, will the bq78350 settings remain in tact, or will it have to be recalibrated.

Thank you for your time. I am sorry for my confusing language.

The bq76940EVM contains a blank bq78350. The function of the bq76940 may be evaulated as is, but the bq78350 must be programmed when its file is available before it will operate.

Yes, the bq78350 will retain settings through a power outage, once it is programmed.
