Operation Theory
4.2.2 Common Power (Sourcing Current)
To connect these signals, connect an external +5 V to +30 V
DC
power supply to <VDDm>, connect <IGND> to ground, and cross
the load between <I_DOn> and <IGND>.
Figure 4-3: Common Power Output Architecture Block Diagram
Note
:
Make sure that VDDm is connected to the positive pole of
DC power and that IGND is connected to the negative pole
of DC power. Damage could be occurred if the connection is
not proper.
Note
:
V5V pin pr5 V power from onboard DC/DC convert
-
er and the maximum current of V5V can only up to 150 mA.
Drawing current more than 150 mA may cause voltage drop
or damage this power supply.
