    Hi Darren,

    This device does not have UVP nor any current protection. Perhaps tell me what battery configuration you are doing (how many cells in series and we can maybe recommend a different one. If you are doing anything 3S or higher use bq77905 if you are doing 2S use bq28z610 as that has build in protection.

    Thanks

    Miguel
