    L9965T-TR

    Automotive SPI to isolated SPI transceiver

    Parameters
    ECCN USEAR99
    ECCN EUNEC
    Packing TypeTape And Reel
    RoHs compliantEcopack2
    GradeAutomotive Safety
    Package NameLQFP 32 7x7x1.4 mm
    Description

    In BMS systems, the L9965T SPI transceivers allow communication between isolated devices in different voltage domains through a twisted-pair connection.


    The devices belong to the L9965 chipset family for the monitoring and control of high-voltage battery management systems.
