  • RE: LM5100A: Gate Driver HO and LO outputs do not display expected signals

    Resolved
    Hi Chris, LM5100A has CMOS inputs that require a higher voltage to drive: The 3.3V square wave is not passing the 5.4V threshold, so the outputs stay low. The LM5101A has TTL inputs that can be driven with a 3.3V signal. Please let me know if there are…
