ACS712 Current Sensor Circuit Diagrams and Datasheet

Last Updated on May 15, 2025 by Swagatam Leave a Comment

Here we are going to learn one cool and very important current sensor device which we call ACS712. This small chip that look just like a normal 8-pin IC, is actually able to sense current from any load and give us a proportional analog voltage output which we can easily feed to Arduino or any […]

Real MPPT Solar Charger Circuit Using Arduino, LCD, and Manual/Auto Switch

Last Updated on May 19, 2025 by Swagatam 4 Comments

So in this article we are trying to make a true MPPT solar charger project using Arduino which will charge a 12V battery from a solar panel and will use MPPT logic to always extract maximum power from the solar panel. That means that even when sunlight changes, we try to adjust PWM duty cycle […]

Do We Need a Freewheeling Diode Across the Inductor in Boost Converter?

Last Updated on May 11, 2025 by Swagatam Leave a Comment

So here we are trying to understand whether we must put a freewheeling diode directly across the inductor in a boost converter or not, to safeguard the switching transistor? How Boost Converter Works So in a boost converter, we got one inductor, one power switch like a MOSFET, one diode and one output capacitor. Input […]

How Load Conducts in Half-Bridge Driver Circuits like IR2184 or IR2110

Last Updated on May 4, 2025 by Swagatam Leave a Comment

Many folks, especially beginners, they get fully confused when they try to use a half-bridge driver circuits using ICs like IR2184 or IR2110. They look at the datasheet diagram and start thinking, “Bro, how the load will conduct? The MOSFETs are switching one by one so how the current will pass through the load? Looks […]

IC IR2184, IR21844 Half-Bridge Driver Circuit Diagram, Datasheet, Working

Last Updated on May 1, 2025 by Swagatam Leave a Comment

In this article we are going to learn about one very useful IC called IR2184 or IR21844. This one is a smart half-bridge gate driver IC which we can use for driving both high-side and low-side MOSFETs or IGBTs, mainly when we are making full bridge inverters, or DC motor controllers, or even induction heater […]
