Dears,

Please help to confirm whether TI BQ27Z746YAHR has Authentication function? This should be DUM key.

This IC if I want to use this function should need to extra payment or not?

Thanks

Hello Ning,

Please reference section 10 of the technical reference manual of the battery gauge but it does not have an "DUM Key" rather it uses SHA-256 authentication .

Thank you,
