4.5.3 General purpose outputs
There are 2 general purpose outputs (OUT_0 / OUT_1). Both outputs are open collector outputs and can drive
loads up-to 100mA. Especially for inductive loads a freewheeling diode to supply voltage (VDD) has been
included. This is also the reason why the external voltage at the general purpose outputs - when the
outputs are switched off - should not be higher than the supply voltage of the module + approx. 0.5V.
