Part Number: TIDA-010247 Other Parts Discussed in Thread: ISO1640 Hi,
Looking at the TIDA-010247 reference design I am struggling to understand the purpose or R112 and R118 that are connected to the top and bottom REG2 outputs respectively.
I found the…
Part Number: BQ76942 Other Parts Discussed in Thread: TIDA-010247 Dears,
We refer to TIDA-010247 to do 2pcs AFE stack design to meet the requirements of 24-string battery applications;
TIDA-010247 can only be directly controlled by the High AFE, and…
Hi Tayyar,
Yes, you can do that. I recommend looking at TIDA-010247 for reference, which implements the bq76942 in a stacked configuration with isolated communications.

HI Luis
Thanks for your feedback.
I2C isolator will be used between MCU and upper AFE as mentioned in TIDA - 010247
In order for MCU to get data at the same time from both the AFEs what address we need to set? are you talking about I2C address.
Also what…
Hello Harish,
You can take a look at the TIDA-010247 reference design to see a stacked high-side FET implementation.
For low-side FETs, you can look at the Using Low-Side FETs with the BQ769x2 Battery Monitor Family application note. Stacking is similar…
Part Number: BQ76952 Other Parts Discussed in Thread: TIDA-010247 , BQ79616 Hi team, What is the maximum number of cells that can be stacked with BQ76952 ? Is 32 the maximum ( two BQ76952 ) with a design similar to TIDA-010247 or can we go beyond 32 cells…
Hi,
I recommend looking at this reference design for a high-side stacked application: TIDA-010247 reference design | TI.com .
The schematic shows how LD and PACK can be implemented on both the upper and lower devices.

Part Number: BQ76940 Other Parts Discussed in Thread: TIDA-00792 , BQ76952 , TIDA-010247
Hello, We are using BQ76940 in our BMS. The system consists of a logic board and a power board. The current sense resistor is located in the power board. The connection…
Part Number: BQ76952 Other Parts Discussed in Thread: TIDA-010247 We are working on a 24S battery management system with 2 BQ76952 ICs and high side mosfets based on TIDA-010247 . We are facing issues in performing short circuit event detection and protection…
Hi Star,
The answer depends on whether the FET configuration is high-side or low-side.
For high-side, see the TIDA-010247 reference design schematic for how we recommend connecting the LD and PACK pins on both devices.
For low-side, see the figure below…
