4.6.3 General purpose outputs
The TMCM-6110 offers two I/O connectors with 8 outputs altogether. All outputs are open-drain outputs. For all
outputs a freewheeling diode (to V
DIGTAL
) is already integrated.
Nevertheless, two output offer more powerful MOSFET driver transistors supporting currents up to 1A. All other
have been designed for currents up to 100mA.
Please note: If V
DIGITAL
connection of the I/O connectors is used for supply of substantial current to any external
circuit please make sure to connect V
DIGTIAL
in addition to V
DRIVER
of the power supply connector.
