PIN #

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.

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..

Logic Input

Chip Enable. LOW logic level switches OFF all Power

MOSFETs.

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

VREF

Logic Input

Current Controller Reference Voltage.

Do not leave this pin open or connect to GND.

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.

VBOOT

Supply Voltage Bootstrap Voltage needed for driving the upper Power

MOSFETs.

OUT3

Power Output

Output 3.

VSB

Power Supply

Half Bridge 3 Power Supply Voltage. It must be

connected to the supply voltage together with pin VSA.

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.

OUT2

Power Output

Output 2.

VCP

Output

Charge Pump Oscillator Output.

Sensor Input

Single Ended Hall Effect Sensor Input 2.

Sensor Input
