Sequential timer circuit

The 556 double timer transports the first half to the latter half by 0.001μF coupling capacitance, giving a total delay which is equal to the sum of single delay. The moment of 6-pin grounding can start the first half of timer. After determining the time interval by 1.1R1C1, the second timer starts delaying, the value is decided by 1.1R2C2. (View)

Long pulse timer circuit

Published:2011/4/2 3:17:00 Author:Nicole | Keyword: timer

Long pulse timer circuit
This timer circuit can provide 20min counting time delay. It is a normal decline oscillator with FET current source. Resistance R1 provides reverse migration to the door of JFET transform into power supply. It colses JFET and delays the charging time of C1. C1 is a low drain capacitance similar to polyester resin.
