    I pulled an old part out of the junk
    drawer, and I'd like to find some info
    on it.

    I seem to recall it being a Hall Effect
    sensor, but I could be wrong. It's
    similar to a TO-92 transistor, but
    both faces are flat.The markings are:

    4644
    5-22
    244 (2) <- small '2' in a circle

    Does this ring a bell with anyone?

    Circle-2 is an old Sprague Logo, so it probably is a hall effect sensor.
    But their part numbers were something like UGN-3xxx or UGS-3xxx. They had
    both analog and digital (built in schmitt trigger amp) output types.
