BQEVSW: bq30z55 software

Part Number: BQEVSW
Other Parts Discussed in Thread: BQ30Z55, BQ30Z554-R1

Hi. I'm searching for proper bqevsw version for bq30z55 ( 550_1_05_1_0013 ), but it seems to be a custom chip. Can somebody please contact me to resolve this issue?


  • Hi Ruslan,

    The information about bq30z55 (that includes FW, tools) is only divulged under NDA. If your company does not have an NDA in place for this device, there is a legal jeopardy involved and you should discard all information you have about this device.

    If your project requires a device similar to bq30z55, I suggest you look at bq30z554-R1 (catalog device) on If your project has more flexibility, I recommend you look at bq40z50-Rx (catalog device, much more recent, more features).
