I intend to control a motor via H-bridge L6205N (PowerDIP20). H-bridge's logic input requirements are:
High level logic input voltage: 2-7 V
High level logic input current: 10 μΑ
Motor's supply requirements are: 9 V, 0.4 A (approximately). Logic signals are the output of a BeagleBoard-xM (0.44 V). Thus, I have to customize signals to >2 V and <10 μΑ.
I thought of putting a 47 kΩ resistor, to customize amperage to 9.3 μΑ (via Ohm's law) and thereafter an non-inverting amplifier (close loop gain equal to 5) to customize voltage to 2.2 V.
Is my syllogism write and if not what is the way customizing both voltage and amperage? Is there something I have to pay attention for this circuit design?
