    Hi Lillian,

    Thank you for posting to E2E.

    The closest TI device alternative would be the S version of UCC5350 (UCC5350SB). This TI gate driver is pin to pin compatible with 1ED3142MU12F with key differences being:

    • Drive strength: 1ED3142MU12F +6A/-6.5A vs UCC5350SB +5A/-5A
      • Drive strength can be addressed by lowering external gate resistance value
    • UVLO: Both drivers have different UVLO's that may be targeting specific FET requirements
      • Do you know the FET part number being used?
        • 1ED3142MU12F UVLO
        • UCC5350SB UVLO

    Best regards,

    Andy Robles
