Functions

Output current detection

Connect a resistor between this pin and ground.

28

RF

The output limitation maximum current, IOUT, is set to be

0.26/Rf by this resistor.

VH

WL

Outputs (that are used to drive external transistors).

The PWM duty is controlled on the UH, VH, and WH side of

these outputs.

36

WH

VCC2

Output block power supply

37

VCC2 Control block power supply

38

VCC1

Short VCC1 to VCC2 and, for stability, insert a capacitor

between these pins and ground.

VCC1

39

IN3–

Hall-effect device inputs.

40

IN3+

The input is seen as a high-level input when IN+ > IN–, and

41

IN2–

as a low-level input for the opposite state.

42

43

IN2+

IN1–

If noise on the Hall-effect device signals is a problem, insert

capacitors between the corresponding IN+ and IN– inputs.

IN1+

The logic high state indicates that VIN+ > VIN–

12
