The time delay circuit composed of transistors and comparators
The time delay circuit composed of transistors and comparators
In Figure 2 is the time delay circuit composed of transistors and comparators. The circuit is like the circuit that is shown in Figure 1, the comparing circuit is the comparator integrated chip M51206l, which is not affected by the environment temperature change and power supply voltage change, therefore, it's stable. If VT2 is made of the Darlington power transistor, the circuit can drive large current loading. Figure 1 Figure 2
