Part Number: BQ76940EVM Other Parts Discussed in Thread: BQ76940 , TIDA-01093 Dear all:
I refer to the BQ76940 EVM schematic design 13S Lithium battery protection board,apply to bicycles battery.when sample board discharge 100A current,short circuit…
Hi Manish,
Stacking BQ76952 devices is not supported by design features of the part, but it should be possible with suitable interface circuits. We do not have a reference design for such a design at least at this time. TIDA-01093 is an example of stacking…
Hi Gururaj, Thank you for your interest in BQ76942.
Yes, you can stack 2 BQ76942 for a 20s application. You will need to use an isolation level as explained in the TI Design TIDA-01093 , released for a different monitor but the concept is the same.
Part Number: BQ76930 Other Parts Discussed in Thread: TIDA-01093 Hi experts,
BQ76930 is mass production on customer side. Now they have 3 board back from end customer. The failure rate is 3%. There are 2pcs of BQ76930 in this system. All the failure…

I reference the TIDA-01093 design 20S application.but the TIDA-01093 uses a single series current path for charge and discharge.I desirable to have separate current…
Hello Cherry,
Yes, they could stack two BQ76952 to support up-to 32 strings. However, additional circuitry is required as the part does not have integrated stacking.
We have a Technical Article on how to stack battery monitors for high-cell-count…
Part Number: BQ76930 Other Parts Discussed in Thread: TIDA-01093 Hello
I attached a SCH file.
Could you review the schematic?

Hi Dinesh,
TIDA-01093 shows 2 devices in a stack. A similar technique could be used for more. Loading for isolators on the bottom group may need to be considered, some may need supplied differently to avoid imbalancing the clusters of cells.
Hi Louis,
Of course TIDA-01093 is our standard reference design for stacking 2 of the BQ769x0 devices, it seems you have followed that. Schematic & BOM are provided along with some test data in the design guide. In your schematic:
The F41 circuit…
Hi,
The BQ76940 can work for this project, but you will need to stack two of these devices since they support up to 15 cells each. TIDA-01093 is the best reference design to use as an example. This reference design stacks two BQ76930 (10s) to create…
