BQ76920EVM: Questions Regarding 3S–5S BMS Schematic( bq76920+bq78350-r1a)

Part Number: BQ76920EVM

Tool/software:

Dear All,

Please find attached the 3S–5S BMS schematic for your reference. I would like to confirm a few design points:

  1. When configuring the circuit for 3S operation, is it correct to short P1, P2, P3, and P4, and to populate C4 and C5 with 0-Ω resistors?

  2. Regarding the TS connection: is the current implementation correct? Should a 10-kΩ fixed resistor be placed in parallel? Additionally, if an external temperature sensing wire is required, how should the circuit be modified accordingly?

  3. Are there any other potential issues in the schematic that I should be aware of? I would greatly appreciate your feedback.

Thank you for your assistance.

Best regards,

Noah
