BQ76920: UL991 Compliance

Part Number: BQ76920
Other Parts Discussed in Thread: BQ7718

Team,

Customer is designing a UL1973-compliant system which requires UL991 compliance. UL991 calls for redundancy or proof of fail safe operation on each critical circuit. Can a battery management system be designed with the BQ76920 and be UL991 compliant? Any documentation would be appreciated.

Thanks,

Antonio

    Hi Antonio,

    Usually the UL requires that the system abide by this so it doesn't directly affect the IC. I couldn't really find this spec online as it is only available for purchase, but i could see that if redundancy is needed, then you will need to work with the customer to know what redundant protection is needed and perhaps we have a protector they can use for 2nd level protection such as the bq7718

    Thanks
