Pin function
• Pins provided for heat dissipation. These pins must
be electrically open.
• Power supply for blocks other than the output
block.
• Speed pulse output 1
A pull-up resistor is built in.
• Speed pulse output 2
A pull-up resistor is built in.
• Hall inputs. The logic high state is when IN+ > IN–.
• Forward reverse control
• Ground for blocks other than the output block.
The RF pin voltage will be the lowest potential
taken on be the output transistors.
