How to turn off 555 Timer for a period of time after Vout signal passes through

Question

I have a single-shot 555 Timer. After triggering, output goes high for a period of time.

What I would like to do now: After Vout goes high and then low again, I want to disable the 555 timer for a period of 10 seconds. During this period, if trigeer signal is activated, it would not set Vouth high.

My theoretical idea is to delay a trig signal for a length of anticipated Vout (50ms-100ms). This delayed trig signal would go to Trig pin of another 555 Timer. This timer would generate Vout2 10s long. Then, I would add a MOSFET - Drain to Reset pin of first 555 Timer, Source to GND. Vout2 would be connected to gate, and on activation it would pull Reset of first 555 Timer to GND and disable the circuit for 10s.

Problem with circuit: How to delay trigger signal?

Other suggestions also welcomed.

Thanks.

Thanks!

Answer 1

Use two 555 chips. The falling edge of the first one's output triggers the second one to hold the first one in reset for 10 seconds.
