BQ34Z100-G1: failure

Part Number: BQ34Z100-G1
Other Parts Discussed in Thread: BQ78350-R1, , BQSTUDIO, BQ-HI-PRODUCTION, EV2400

hi,

We have a project based on bq78350-R1 as controller and  bq34z100-g1 fuel-gauge.

Currently we program them via a software developed by a 3rd part, but we have suspicion it doesn't work well... 

We have about 30 units (out of a first batch of 1500), on which one of this IC's are somehow crashed or are in locked state.

We tried to reset Power Supply on them and "force" program via BQstudio, but it didn't help.

I tested BQ-HI-Production [http://www.ti.com/tool/BQ-HI-PRODUCTION], but it was impossible to run 2 versions of this program (for bq78350-R1 and bq34z100-g1) on the same station simultaneously, so this is not an optimal solution for production line.

Can you please advice us some solution for programming bq34z100-g1 and bq78350-R1 on same workstation?

how can we do that?

thanks a lot in advance

KR

Vincenzo

    Hi Vicenzo,

    Unfortunately, these devices are currently supported by different version of bq-hi-production. The 78350 version only allows the EV2300 to be used. Please try attaching the EV2300 to the system and bringing the 78350 version of bq-hi-production.

    Once confirmed operational, attach an EV2400 and bring up the 34z100-g1 version of bg-hi-production.

    If this bring up strategy does not work, please let us know.

    Sincerely,
    Bryan Kahler
