Tool/software:
Hello TI Team,
We are developing a 16S, 50A Li-ion BMS using the BQ76952 and would appreciate your feedback on our schematic and PCB. The design incorporates external N-channel MOSFETs for cell balancing (VCn–VCn–1 topology), low-side current sensing, and CHG/DSG/PCHG FETs for load control.
The schematic follows the TRM and EVM guidelines, and we seek your inputs, particularly on the cell input filtering and protection network, balancing FET drive circuit (Rbal, Rgn, Rn values), gate drive design for CHG/DSG/PCHG, current sense filtering and power handling, and overall signal integrity and reliability for high-current operation.
Please connect, and I will share the schematic and PCB for review.
Thank you,
Saif Shaikh
