Hi Anil,
We do not recommend using the active balancing reference design with bq79606a as our reference was for bq76pl455a. If you decide to use our newer devices (bq79606a or bq79616) which we recommend, then we advise to use passive balancing solutions…
Hi Cameron,
For auto rated devices, I recommend reviewing datasheets for bq76pl455a (16 channel), bq79606a (6 channel) and bq79616 (16 channel) in order of release date. They all should meet most of your requirements and usually require an external…
Part Number: BQ75614-Q1 Other Parts Discussed in Thread: BQ79616 , Team,
Do we have some details about what the BUS BAR connection and measurement refers too? What is the typical use case in which it is used? Can it be used for interchangeably for current…
Hi Nivethitha,
Take a look at bq79606a and bq79616, these are battery monitor/balancer/protectors for automotive/ESS applications. They do passive balancing which is a more cost-effective solution. They both have timers to indicate when each cell has…
Hi Massimilano,
The bq76pl455a device does not reclock the daisy chain signal between each device so I would say it may start to deteriorate with more than 6 devices in a stack (depending on cable used and pcb design and noise). Would you consider using…
Hello Hamzeh,
Besides the BQ769x2 family of devices, which the BQ769142 is part of, and the BQ769x0 family; both which need more considerations to stack, I would say you could look into our automotive-grade monitors, like the BQ79616-Q1 . These are…
Hello Tamas,
You should consider looking at the BQ7961x family of devices. They have features similar to what you are requesting. https://www.ti.com/product/BQ79616-Q1?keyMatch=BQ7961
UART and FAULT lines are same-PCB communication, so we have…
Hi Devayani,
Please take a look at the bq79606-Q1 (released) or bq79616-Q1 (to release soon). These AFEs are designed to be scalable, functional safety capable, and specifically targeted for automotive BMS solutions.
Best Regards,
Taylor
Hi user,
I would follow datasheet recommendation first but ultimately with EMC, it requires some experimenting depending on your board layout, cable, placement, specification etc. This device was validated for these tests many years ago and we have…
Hi Taylor,
Thanks for the quick reply.
That's bit surprising; because, datasheet says that upto 16 ICs in Daisy-chain with twisted pair cables should work.
We only have very short twisted pair cables between BMSs and there are only 12 of them…
