The time delay circuit diagram composed of transistor
The time delay circuit diagram composed of transistor

(a) Timedelay circuit (b) Timedelay circuit It can set delay time according to the voltage Us and resistor R. In the circuit, S1 is the the discharge switch of capacitor C. When the switch S1 is closed, the stored charge on C will be released through S1 to ensure the accuracy of the delay time the next time. VD1 and VD2 are used to eliminate the impact of VT1 by its voltage UBE. In the circuit, the load current can be only 5OnA. If VT3 is replaced by Darlington transistor, the load current will be increased. VT1 uses 2SC1815; VT2 and VT3 use 2SAlO15; VD1 and VD2 use 1S1588. Delay time T = RC1n1 / (1-K), K = Uc / Us. Figure 1 (b) is a time delay circuit composedof the transistor and the comparator. It is similar with the circuit shown in Figure 1(a). The comparison circuit uses comparator integrated chip M51206L. It is not effected by environmental temperature and supply voltage variations. Therefore, the circuit is very stable. If VT2 uses the Darlington power transistor, you can drive higher current load.   (View)

Simple current limiting circuit

Published:2011/9/12 21:59:00 Author:John | Keyword: current limiting

Simple current limiting circuit
Simple current limiting circuit

When the current is less than the value set, the bias current provided by R1 leads the P3 to be saturated to conduct. And it can not afford to control the current. When the current is greater than or equal to the set value, the pressure drop on R would increase and be close to the pressure drop of R2 after acrossing the transistor junction. Then it can limit the current through P3 in order to limit the current to a certain level. If R2 is used as a regulator instead, the limiting performance can be more accurate. The drawback of the introduced protection circuit is that the pressure drop can be all down on the transistor when the current is overload, especially a short circuit. Thus, it would lead to certain power consumption.   (View)
