3.5.4 General Purpose Outputs
The TMCM-1310 offers two I/O connectors with 8 outputs altogether. All outputs are open-drain outputs
and a freewheeling diode (to V
DIGTAL
) is already integrated. Six outputs are designed for currents up to
100mA and two outputs offer more powerful MOSFET driver transistors supporting currents up to 1A.
If the V
CC
connection of the I/O connectors (connected internally to V
DIGITAL
) is used for the supply of
substantial current to any external circuit, make sure to connect V
DIGTIAL
to V
DRIVER
of the power supply
connector.
