INA219 Current Sensor Circuit Diagram and Datasheet

Last Updated on May 16, 2025 by Swagatam Leave a Comment

In this post we are going to understand this sensor called INA219, and this one is like a full smart sensor. It not only tells how much current is flowing but also tells voltage, and also calculates power, all in digital form. That means it talks with microcontroller through I2C lines. It is like an […]

ACS712 Current Sensor Circuit Diagrams and Datasheet

Last Updated on May 15, 2025 by Swagatam 1 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 […]

Step-Down Adjustable Voltage, Current Regulator Circuit using LM2673

Last Updated on February 7, 2025 by Swagatam Leave a Comment

The LM2673 series of regulators is a collection of monolithic integrated circuits that are designed to provide all the active functions needed for making a step-down, or buck converter, switching regulator circuit. This means that they are capable of driving loads of up to 3 amps while maintaining excellent line and load regulation characteristics. One […]

Adjustable Voltage Regulator Circuit using LM324 IC with Over Current Protection

Last Updated on February 17, 2024 by Swagatam 4 Comments

LM324 voltage regulator circuit

In this post I have explained how a single LM324 IC can be used to create an adjustable voltage regulator circuit with overload and over current protections. Basic Working A basic IC LM324 quad operational amplifier regulates an unregulated 28-volt input source to approximately ±0.02%, resulting in a 1 amp 0 to -20 V supply. The […]

How to Measure Very Low Current [Circuit Diagram]

Last Updated on February 9, 2024 by Swagatam 3 Comments

very low current measuring meter circuit

Accurately measuring very low currents of a few microamps or less using a regular panel meter or multimeter is not feasible. To make such precise measurements, you need to employ an active circuit, like the one depicted here. This circuit low current ammeter circuit can be constructed as a self-contained unit or integrated into an […]
