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.

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..

Logic Input

Chip Enable. LOW logic level switches OFF all Power

MOSFETs.

If not used, it has to be connected to +5V.

Logic Input Current Controller Reference Voltage.

Do not leave this pin open or connect to GND.

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.

Supply Voltage Bootstrap Voltage needed for driving the upper Power

MOSFETs.

Power Output Output 3.

Power Supply Half Bridge 3 Power Supply Voltage. It must be

connected to the supply voltage together with pin VSA.

Power Supply Half Bridge 1 and Half Bridge 2 Power Supply Voltage.

It must be connected to the supply voltage together

with pin VSB.

Power Output Output 2.

Output Charge Pump Oscillator Output.

Sensor Input Single Ended Hall Effect Sensor Input 2.

Sensor Input Single Ended Hall Effect Sensor Input 3.
