BQ77915: Schematic Review

Part Number: BQ77915

Tool/software:

Hello E2E Experts, 

God day.

I would greatly appreciate it if you could review the attached schematic for any necessary corrections or improvements.

The schematic is attached to the next message in PDF format with the list of specifications.

Your expertise in checking this schematic would be invaluable to ensure the design meets the specified requirements. If you have any suggestions or corrections, I would be grateful for your feedback.

The specifications for the system are as follows:

Pack voltage range: 14V - 12V
Cell normal charge voltage: 4.2V
Cell cutoff voltage: 2.8V
Over-current trip point: 3.5A
Max ambient temperature: Around 40°C (Approximately 38°C inside the enclosure)
Cell configuration: Selected to provide 4.5 Ah over the system range of operation
Cell balancing: Desired with a current around 10% of termination current
Load removal for fault recovery: Required
(Recovery by connecting the charger is acceptable, as the application of the battery pack could not physically disconnect the load easily)
