FUNCTION
Constant output voltage of 2.5V (typical). Make
connections from this pin to a potentiometer or
pulse stretcher resistor.
Connect the capacitor and resistor of the pulse
stretcher section.
Dead band setting by connecting a capacitor.
Input signal, an adjustable pulse of 20ms cycle and
1.0-2.0ms pulse-width, operate with a positive
pulse of peak value 3V or greater.
Timing Resistor, connect a resistor that will
determine the value of the constant current of this
pin. A resistor of 18kΩ will yield a current of
1.0mA.
Local pulse setting, connect a capacitor that will
generate a triangular wave by constant current
charging.
Output Driver 1 (connect to motor)
