5.8 General purpose outputs OUT0..3

The TMCM-3212 and TMCM-3213 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).
