Parameter:
Main chip: NE555
Input voltage: DC 5V-15V
Input current ≥ 100MA
Output current: 15MA-35MA
Output amplitude: 4.2V-11.4V V-PP
Maximum output current:
≥ 15MA (5V supply, V-PP greater than 50%),
≥ 35MA (12V supply, V-PP greater than 50%)
Application scope:
1. It is used as a square wave signal generator to generate square wave signals for experimental development and use.
2. Used to generate a square wave signal that drives a stepper motor driver.
3. Generate adjustable pulses for use by the MCU.
4. Generate adjustable pulses to control the associated circuitry.
Features:
1. Output with LED indication; (the LED is on when in the low level, the LED is on when in the high level, and the LED is flashing when the frequency is low)
2. The output frequency range is optional (use the short-circuit cap) to make the output frequency more continuously adjustable;
low frequency range: 1Hz - 50Hz
intermediate frequency range: 50Hz - 1kHz
high frequency range: 1KHz - 10kHz
high frequency range: 10kHz - 200kHz
3. The output duty cycle can be fine-tuned, the duty cycle and frequency are not separately adjustable, and the duty cycle is adjusted to change the frequency.
4. The output frequency is adjustable;
cycle T=0.7(RA+2RB)C
RA, RB is 0-10K adjustable;
C=0.001UF at low frequency;
in the middle frequency range, C=0.1UF;
in the high-frequency file C=1UF;
high frequency file C=100UF
