The IC is one of those devices which promises an unlimited range of circuit application solutions. The IC is so versatile that on many occasions it easily outsmarts it's close rival, the IC , let's study the datasheet and pinout details of this versatile chip.

Complementary push-pull outputs with a separate active clock output, the clock output is actually an extension of the internal oscillator frequency output. In the astable mode the chip provides the option of integrating external triggering inputs, also called true gating and complement gating modes.

The monostable mode enables positive edge triggering as well as negative edge triggering of the IC. Meaning after the normal trigger is applied to the IC, more number subsequent triggers can be applied so that the output adds up the timing, generating further delay at the output.

The following explanation suggests how the pinouts of the IC may be configured for implementing the above discussed operating modes:. For the above modes, the output may be obtained across pin 10, 11 push-pull while clocks at pin As shown in the figure above, the IC can be used as a free running astable multivibrator or oscillator by configuring the chip in the above suggested method.

Basically R1, P1 togeter must not be less than 10K, and above 1M, while C1 should not be less than pF higher value have no restrictions in order to maintain proper functioning of the chip.

Pin13 is normally kept open when not in use, it may be applied in cases where a frequency or pulsed output may be required for the other stages of the circuit for enhancing purposes, such as for making modified PWM based inverters etc. One typical simple square wave inverter application using the IC can be witnessed below:. If you have any circuit related query, you may interact through comments, I'll be most happy to help!

Your email:. I live out in the dessert off grid and have no electric or running water. Now I need an inverter. Could you recommend some reading that would most quickly givee the knowledge to know how to make one.

Thank you. Signed no more utility bills. Adrian, there are some inverter designing information explained in the following article, which you can refer to for understanding the basic inverter working concept. Dear swagatam It seems that definition of drain and source pins of IRF is mistake in your diagram.

Please correct that. According to me those are not relevant to the ICs main technical specifications, so far whenever I have purchased ICs I have looked into the main number for example in this case only the is relevant and important rest of the things can be ignored….

Again thanks for answering, another one are different manufacturers have same dimensions of IC for example I have to replace it on PCB board the dimensions of the hole are same? I use ic for ocillator and mosfet is IRF use I doing a tryed to 1 Chang old to new mosfet 2 inter changing of mosfet 3 transformer connection Chang 4 Chang with mosfet gate connection to each other.

I think the oscillation is not working. Can you please tell why this is happening? If the IC is configured correctly then it should work, there are only two parts that needs to be connected with the IC for a proper working of the IC…. But the datasheet says Tosc is 2. So how you end up in above equation? However if I set my multimeter in AC and check the output of the ic I get 27v. Instead of 12v or 6v. I also checked AC current in the battery there is also showing 27v.

I think the capacitor is placed incorrectly. Can you tell me which side I should place anode and cathode? The way you have soldered looks very messy, you must clean the soldering with acetone or some cleaning agent, mosfets are extremely sensitive devices sand will burn with slightest inaccuracy. I built this circuit using cdBCN, irfpn but it is not working when ever I connect it I get short circuit. Am i right? Is there any specific formula to calculate it?

Tushar, across which points did you check the voltage? Hello Paras, no it is not possible to make a 3 phase inverter using a IC…..

So at the output i'll get Vac 50Hz? I want to increase the input voltage 12v to 24v what changes I have to done with the circuit??? Sir, this project uses PWM, high frequency is generated. What type of transformer used: ferrite, siliceous iron sheets EI. I want built a W solar inverter for project …. Hi sir, Can you explain me what is oscillator and what is its work. I am new in electronics. Hi Mayank, an oscillator is a circuit which is able to produce alternate positive and negative voltages at its output at a given specified frequency.

Sir i have designed inverter 12v dc to v ac using IC, it's output is well enough when ever i test in bread board but when i do solding and wireing output voltage drop too much, whats the reason for that?. Wasiq, PCB assembly will normally produce better results than breadboard, so your problem could be due to some hidden fault…..

Your email address will not be published. Notify me via e-mail if anyone answers my comment. You'll also like: 1. I admire your patience on answering all these comments. Thank you dear Fereidoon for notifying, I have changed the diagram now! I do not have the exact values you may have to practically check it and fix it…. Thanks for answering. I checked the output using multimeter and the output is equal to input. Hello sir, am just joining now, I want to build a pure sine wave inverter.

Sir,what are demerits of square wave inverter to home appliances? Hello Mayank, you can make a watt inverter by using IRF or any similar mosfet…. Dear Friends, 1 Please make sure your comments are related to the article topic, for example a motor related comment should be posted under a motor related post, a battery charger question under a battery charger post, voltage control under power supply article and so forth Thank you for your consideration Search this website.

We can use the IC in both Astable and Monostable mode, for making different circuit. The IC can be used for generating clock pulse, sine wave, square wave and many others. It can also be used in application of timing delay circuits, frequency multiplier and frequency divider. To generate an envelope signal from the original signal this IC is helpful. It needs an external resistor to be connected between PIN 1 and 3 to determine the output pulse width in Monostable mode.
