    Normally open transistor to control the inhibit of a driver from Teensy 3.5

    Hi everybody,

    I am using a driver Advanced Control Driver 12A8-QDI to control a DC motor from Teensy 3.5.
    I would like to control the inhibit pin of the driver to be sure that it is disabled/enabled when I want.
    The inhibit pin enables the driver when it is connected to ground and disabled it when it is open or connected to 5V.
    I was thinking about using a digital pin of Teensy to control a transistor connected to the driver inhibit pin.

    Could you suggest me a cheap transistor normally open suitable for this application?

    Thank you.

    A BS170 would work and no extra parts needed.

    Thank you rcarr!

    I have solved the problem with a TIP120 that I already had in the lab.
