About BQ33100EVM

Hello,

I bought two bq33100EVM to do a supcap balance project. I have few questions about it when dig it.

1. How can I know my bq33100evm is sealed or unsealed package? Because I tried to read SMB command and send SMB word all got the error code: No Acknowledge: VB_T2H_NACK.

2. Do the flash write only can be done by unsealed package? I tried to write 0x0308  the Operation Cfg, nothing change. I want to set the supcaps numer from 5 to 4 counts.

 

Thanks

 

Yale
