555 Negative voltage source circuit

Published:2011/4/27 3:47:00 Author:Ecco | Keyword: 555 , Negative, voltage source

As shown in Figure 9-1, 555 and R1, R2, C3 form an astable multivibrator, f = 1.44 / (R1 +2 R2) C3, the frequency of the icon parameter is about 80kHz. R2 is greater than the R1, so the duty cycle closes to 50%. The output oscillation pulses is rectified by the D1, D2, C2, and it gets a negative voltage and offers tens of mA load current.   (View)

555 voltage detection circuit

Published:2011/4/27 3:41:00 Author:Ecco | Keyword: 555, voltage detection

As shown in Figure 7-10, the voltage detection circuit uses 555 as the core to form in bistable mode. Usually, the pin 6 of 555 (threshold level side)is connected to VDD by R1, therefore, pin 3 is in low level. The pin 2 on trigger end of 555 is connected to the measured point by a regulator DW, DW regulator is Vz, when the measured voltage is less than Vz +1/3 VDD, the 555 sets, pin 3 is high level, LED is lit. If using different value of regulators DW, it is controlled by the switch, you can distinguish the different values ​​of the measured voltage.   (View)

555 quickly resistance measuring circuit

Published:2011/4/27 3:32:00 Author:Ecco | Keyword: 555 , quickly , resistance, measuring

As shown in Figure 7-8, measuring circuit uses 555 as the core, and 555,R1, R2, R3, Rx, C1 form an astable multivibrator. Changing the switch K can change the oscillation frequency. Since R4 ~ R9 resistor (10Ω ~ 1MΩ) is known, Rx is the resistance under test,it caneasily and quickly determine the resistance of Rx by the comparison of the sound with correspondingoscillation frequency of known resistors.   (View)
