SENSEB
Power Supply
Half Bridge 3 Source Pin. This pin must be connected
together with pin SENSEA to Power Ground through a
sensing power resistor. At this pin also the Inverting
Input of the Sense Comparator is connected.
11
26
FWD/REV
Logic Input
Selects the direction of the rotation. HIGH logic level
sets Forward Operation, whereas LOW logic level sets
Reverse Operation.
If not used, it has to be connected to GND or +5V..
