    Dear TI-er.

    TL751M05-Q1 is 60V LoadDump Protection.

    Is it for 24V automotive battery system(input min 24V ~ max 32V) ?

    plz help me.

    Hello ElSalvador,

    TLE4275 may be able to handle 55V load dump; however, this is not something that TI can guarantee since it is past abs max spec. As suggested, TL751M05 is a good alternative.

    From the datasheet, Vi (max) is 26V.  Therefore, a 24V battery system will be ok to handle a 60V load dump. The device may be able to handle 60V load dump with Vi = 32V; however, once again, this is not something TI can guarantee since it is not within the datasheet limits.

    Best Regards,
