  • UCC27614: Mosfet Driver

    TI Thinks Resolved
    Part Number: UCC27614 Tool/software: VM voltage is 48V. VCC voltage is 8V 100mA. Does 8V 100mA prevent the mosfet driver from driving the mosfet? Other than that, do you see any problems in the schematic? Thanks.

  • UCC27614: Failure at very light load.

    TI Thinks Resolved
    Part Number: UCC27614 Tool/software: Hi, We are developing a new product which uses two UCC27614 to drive each transistor in the MSCSM120DUM027AG. Our gate driver board had the wrong footprint for the UCC27614, so we turned it upside down and patched…
