TECHNICAL APPLICATION NOTES

PIN DESCRIPTION

1. Servo Position Voltage Input Pin (Pin 1 )

Connect the potentiometer terminal for position detection that

follows the output axis. Compare this voltage with the voltage

of the triangular wave of pin 2 and drive the motor. A capacitor

of approximately 0.1µF should be connected for noise

prevention.

2. Timing Capacitor Pin (Pin 2 )

Connect a capacitor that will generate a triangular wave by

constant current charging. A typical value is 0.1µF. Also

connect a feedback resistor from the output here.

3. Timing Resistor (Pin 3 )

Connect a resistor that will determine the value of the constant

current of pin 2 . A resistor of 18kΩ will yield a current of

1.0mA. A capacitor of approximately 0.03µF should be

connected in parallel with the resistor to increase stability.

4. External PNP Transistor Drive 1 (Pin 4 )

Connect to the base of the external PNP transistor.

5. Input Pin (Pin 5 )

Operate with a positive pulse of peak value 3V or greater.

6. Output 1 Pin (Pin 6 )

Connect a feedback resistor between this pin and pin 2 .

7. Ground (pins 7 and 8 )

8. Error Pulse Output pin (Pin 9 )

Connect a resistor between this pin and pin 11 . The dead band

will change according to the value of this resistor.

9. Output 2 pin (Pin 10 )

This is the output 2 pin.

10. Stretcher Input Pin (Pin 11 )

Connect the capacitor and resistor of the pulse stretcher

section.

11. External PNP Transistor Drive 2 (Pin 12 )

Connect to the base of the external PNP transistor.

12. Regulated Voltage Output Pin (Pin 13 )

This is the output of the internal regulated supply voltage.

Make connections from this pin to a potentiometer or pulse

stretcher resistor. Connect a capacitor of approximately 2.2µF

for stability.

13. Supply Voltage (Pin 14 )

The supply voltage exhibits uniform characteristics from 3.5V

to 7V. Connect a capacitor of approximately 10µF.
