Part Number: BQ76940
Other Parts Discussed in Thread: BQ76942,

Hello,

Since due to unavailability of BQ76942 IC, I have planned to use BQ7694002DBT IC for my 8S cell balancing application. I found out the datasheet of this IC from TI website ,but I have some following doubts:-

1) I am unable to find any example .sch file in the pdf or any suggestion supported components clearly for this IC in the pdf. Could you please provide me the BOM required for this IC along with schematic and pcb layout.

2) Could you also provide me the details regarding how to achieve the external cell balancing features for this IC?

Hi Babu,

There are multiple TI Reference designs for this device that include schematic and layout files. These reference designs are configured for external balancing: https://www.ti.com/product/BQ76940#reference-designs

Also, I recommend the Bq769x0 Top Ten Design Considerations document and the FAQ document (both available on the BQ76940 product page. There is also a video to help guide through creating the schematic: https://training.ti.com/how-create-schematic-bq76920-bq76930-and-bq76940

Best regards,

Matt
