• LTC2966 ltspice result under VinA =VinB=0

    Hi

    I have quetion for  LTspice simulation result. 

    Condition is reference circuit.(open this macromodel's fixture in LTC2966)

    VinA=VinB=GND

    result:

    OUTA=Low 

    OUTB=Low

    But  under VinA=VinB=0V ,this IC don't have supply and can't turn on OUTA,OUTB…
