1

2

IN−

IN+

Input pins for hall element outputs.

3

C

Capacitor pin (1 to 10 µF) that forms automatic return circuit.

When rotation is stopped due to overload, the pin voltage increases and output stops.

After proper load adjustment, the output returns from ‘‘stop’’ mode to ‘‘drive’’ mode automatically.

The lock detect time can be set by changing the capacitor constant.

4

6

OUT1

OUT2

Output pins. The output transistor is Darlington connected.

Connect either an external capacitor or an external Zener diode for output transistor protection.

5

GND

Ground pin.

8

7

B1

B2

Base pins for Darlington connected output transistors.

If radio noise is a problem, add a capacitor (0.01 to 0.1 µF).

9

RD

Open collector output. Drive mode: ‘‘L’’, Stop mode: ‘‘H’’

10

range from 3.8 to 6.0 V.
