    Question

    Thank you Steve!

    VCC = Input voltage
    What is Vbe, Ic, HFE?

    Ic = Collector current
    Vbe = voltage between Base and Emitter
    HFE = Transistor gain, you'll find that one in the datasheet

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    You didn't mention if you need to sink or source current to the device? Either way, have you considered using an N-channel (sink) or P-channel (source) MOSFET instead of a bipolar transistor?

    Regards, Mike

    Hi Mike

    I'm using a PNP transistor to source current.
