  • NE555: Trying to add bias to a-stable mode operation.

    Resolved
    Part Number: NE555 Other Parts Discussed in Thread: LMC555 , TLC555 Hello everyone, I have designed a simple a-stable mode timer circuit (as displayed in the NE555 datasheet) to achieve 60kHz. My problem is that the output goes from 0 to Vcc. I'm looking…

  • RE: TINA/Spice/NE555: 555 timer for 24V,2A Back-up for short duration(300ms)

    Resolved
    Yeah I agree with you. Ideal solution would be through the Supercaps. I just wanted to check whether it's possible through the 555 Timer. Thanks for the clarification. Lakshminarayana K N.

  • RE: NE555: circuit not working

    Resolved
    Ed, Time period is 1.1 * R * C = 1.1 * 10k * .47u = 5.17ms; this is 0.005 seconds Is it true that you wanted 400 to 500 seconds (6 and 2/3 minutes to 8 and 1/3 minutes)? Is your circuit closer to figure 9 or figure 12 in the NE555 data sheet? …

  • RE: NE555: Inductor Oscillator and Timing

    Resolved
    Handy, Do as Mike suggested or there are many other circuits to measure inductance. The 555 doesn't work with inductors directly. Try web search for "inductance meter schematic" for example to see other ways.
