BQ40Z50-R1: Stand alone operation without use of a microcontroller

Part Number: BQ40Z50-R1
Other Parts Discussed in Thread: BQSTUDIO, BQ40Z50

Hi,

Is is possible to operate the BQ40Z50-R1 without connection to a microcontroller during operation?  It is acceptable to initially program the unit with a microcontroller before deployment.

Can I use the IC to trigger an audible alarm/LED when there are X minutes left during operation if I know the current drain?  (Again without connection to a microcontroller during operation)

Thanks,

Kamron

  • Hi Kamron,

    Yes the bq40z50-R1 can be programmed using the bqStudio tool and you can walk through the TRM to go through the process of creating your srec file or using your gg file + identifying a chemID, and this is what you will program in your production line to each pack and you will not need any MCU in the pack from that point on.

    You can configure the LEDs of the bq40z50 to use only one LED if you want and you can set the threshold to a certain SOC % (not minutes) to trigger the LED.

    Thanks

  • Thanks Miguel. I'll give that a try when ready.
