Circuit Description
Circuit Graph
This is a 555 Timer Servo Motor Remote Position Transmitter from NE543 SERVO AMPLIFIER (Servo Amplifier and Pulse Width Demodulator) Datasheet.
This is for 60 Hz servo motors with 1.5 ms ±0.5 ms pulse range. As described in the datasheet, "The servo output moves over 100 degrees for pulses between 1 and 2ms. The pulses occur at 16 ms intervals."
The NE543 has the following supply voltage limits
Minimum = 3.6 V
Typical = 4.8 V
Maximum = 6.0 V
so the circuit is most likely designed for a 5 V system.
Note:
This circuit uses 1N4148 for D1 instead of the 1N457 in NE543's datasheet. The latter is not available in Free Subscription version of Multisim Live.
