BQ76PL455A: Multiple bq76PL455A on the same PCB

AIT GHRIB Abderrahman

Part Number: BQ76PL455A

Hi,

Could you please tell me if I can connect multiple bq76PL455A on the same PCB using the differential communication? If yes, please provide me with the design guidelines.

Many thanks.

Regards,

Abderrahman,

Yes, this is definitely possible. Please refer to Figure 17 of the bq76PL455 design considerations document for reference: www.ti.com/.../slua791.pdf

Section 1.3 of the use case scenarios document also gives a brief explanation: www.ti.com/.../slua785.pdf

One thing to consider is that each 455 ground is referenced to the bottom of the stack it monitors. If you are using multiple devices on a single board, please consider using several "voltage domains"
