5.8 General purpose outputs OUT0..3
The TMCM-3214 and TMCM-3215 offer 4 open-drain (N-channel MOSFET) general purpose outputs available at the
output connector of the interface brick part. The internal connection of the N-channel MOSFETs together with a
flyback / freewheeling diode can be seen in figure 5.8. When activating the MOSFET the related output will be
pulled low (sometimes called npn-style switch).
