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…
Part Number: BQ76PL455A Other Parts Discussed in Thread: BQ79616 Hi team,
Our customer is using BQ76PL455 and they found voltage sensing error increased after using a 390pF cap between out1 and out2 pins, both negative and positive error exists. Error…
Hi annib,
The attachments did not work - can you please rettach? I also want to comment this design is very old and so support knowledge on this design is limited especially for custom designs. Can you comment on if the much newer cost effective devices…
Other Parts Discussed in Thread: BQ77905 , BQ76PL455A , BQ79616 Hello:
I'm looking for a battery protection chip that supports up to 160S battery packs thru SimpleStack stacking interface ,
For example 10S*16=160S，or 16S*10=160S.....
Please Ti engineers…
Sy Yoon,
1 master node is supported. How many CSUs are you planning to support? 32 is the max value that we have tested but the architecture is designed to support potentially up to 100 pending a few tradeoffs. Keep in mind each CSU can supervise numerous…
I looked at the loopback example and I see the only processing done in the receive ISR is assigning
EUSCI_A_UART_receiveData(EUSCI_A0_BASE).
I eliminated other things I had in the ISR.
My setup is MSP-EXP430FR5994 -> BQ79600EVM -> custom BQ79616…
Part Number: BQ76PL455A Other Parts Discussed in Thread: BQ79616 Hi Team,
referring to e2e.ti.com/.../632821 , we understood that the maximum of 140pF cable capacitance is spec'ed between IC to IC.
Is there any spec for the complete daisy chain? …
Hi, I applied 10 s delay, but still, it is not working, I'm trying with only one BQ79656 device.
I'm getting the voltage data perfectly.
I've attached the part of code, please check it once. wakeup_BQ();
init_ASCLIN_UART(); /* Initialize the UART…
