BQ2084 seal/unseal problem

BQ2084 seal/unseal problem

Dear All,

We do development of battery pack based on BQ2084/BQ29312 and I´ve sealed this chip. There is no info how to unseal it in datasheet. BQ2048 evaluation software via EV2300 asks for some passwords. Could you kindly help me?

Best Regards

Michal (Zaky100@gmail.com)
