Ground connection for all circuit except the outputs.
Output pins.
Output-stage supply pin.
Connect a capacitor between this pin and ground to
reduce the control input-output gain frequency
response and to stop the oscillator.
Output transistor ground.
A resistor can be connected between this pin and
GND to sense the output current as a voltage drop to
provide for overcurrent protection.
Supply for all circuits except the output stage.
This supply should be kept stable to prevent ripple
and noise from sntering this pin.
Speed control pins.
Pin 4 voltage determines the control start voltage.
Pin 5 voltage is used to control the output voltage
(voltage control method).
