B
Power Supply Half Bridge 3 Source Pin. This pin must be connected
together with pin SENSE
A
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..
12 27 EN Logic Input Chip Enable. LOW logic level switches OFF all Power
MOSFETs.
If not used, it has to be connected to +5V.
13 28 VREF Logic Input Current Controller Reference Voltage.
Do not leave this pin open or connect to GND.
14 29 BRAKE Logic Input 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.
15 30 VBOOT Supply Voltage Bootstrap Voltage needed for driving the upper Power
MOSFETs.
