If you want to control it from a 3.3 V MCU that can’t handle the high-side voltage on its pins, you can add a NPN transistor section as shown ... This circuit is called a high-side switch ...

An NPN transistor is an electronic component used as a switch or amplifier. It has three legs: base (B), collector ©, and emitter (E). In circuit diagrams, the base is usually in the middle, the ...

We’ll dive into the basics of transistors, including the difference between NPN and PNP types, and explore their crucial role in creating electronic circuits. You’ll learn how transistors act ...

There are numerous differences between NPN and PNP transistors, ... and the basis for nearly all integrated circuits (ICs). The transistor is a three-terminal electronic ... to as switch mode. It ...

In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light.
