Hi Akash,

Ensure that you are using enhancement type MOSFETs for M1 and M2, as the OUT pin is active high. Additionally, I recommend using 1Mohm pulldown resistors from gate to source for your n-channel MOSFETs.

Best,

Andria

Hi,

Thank you.

Can you pls tell which configuration is better: Common drain or Common source

Hey Akash,

TI's references for FET designs in BMS are common drain.

Thanks,
Caleb
