together with pin SENSE
sensing power resistor. At this pin also the Inverting
Input of the Sense Comparator is connected.
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..
Chip Enable. LOW logic level switches OFF all Power
MOSFETs.
If not used, it has to be connected to +5V.
Current Controller Reference Voltage.
Do not leave this pin open or connect to GND.
Brake Input pin. LOW logic level switches ON all High
Side Power MOSFETs, implementing the Brake
Function.
If not used, it has to be connected to +5V.
