In this post I have explained a two op amp IC 741 and LM358 based auto cut off battery charger circuits which are not only accurate with its features but also allows a hassle free and quick setting up of its high/low cut-off threshold limits. High current batteries can e also charged using these circuits. […]

How to Sense Current Using Op-Amp: Low Side and High Side Circuits Explained
In this post we are going to learn one very interesting and also very much useful topic that is how we can measure the current which is going through any load by just using some normal resistors and one op amp circuit. We know already that current is one very important thing in every electrical […]
IC 4047 Astable, Monostable Oscillator Circuits
In an IC 4047 astable oscillator circuit, the output of the IC continuously generates a switching ON/OFF signal. Since the output is never in a stable state and constantly switches between and low and high, it is called an astable multivibrator. The astable ON/OFF switching frequency is adjustable and can be varied by changing the […]
How to Design Customized 220V SMPS Circuits
We many times think that how we can make a SMPS circuit, and we feel that this is very complex. But that is not so because we can do this by following simple manual calculations step by step. We only need to know that SMPS design is always starting from the transformer. We cannot make […]
