Computer Outputs: High-Side and Low-Side Drivers

Computer output signals use transistors to turn on and off or control external devices. There are two types of output circuits: high-side drivers and low-side drivers.

Thank you Justin...you have answered my so many questions in just 6~7 minutes.... finding myself relieved 😌
a concise lecture that has been beautifully presented ❤❤❤

[@s8computers781]

Thank you Justin, this is the best explanation I have found for understanding high side and low side meaning. Really appreciate this👍

You are a natural teacher Justin. Fantastic. You just answered the question I had all along, "but where are the fuses in computer controlled circuits?" I greatly appreciate it.

Aren't you supposed to supply a current of a certain value to the base to switch a transistor on, and not a voltage?

[@mikeadler434]

👍👍

[@arthurfricchione8119]

Just your videos are top notch. Very helpful in giving myself a DIYer John the computer side of this function. Are drivers mostly NPN or PNP?. Thanks for sharing Artie ❤️👍

[@JustinMillerAutomotive]

As far as I understand, high side drivers generally use PNP transistors and low side drivers generally use NPN transistors. However, I think it is technically possible to switch those around.

[@roseelectronics4582]

@@JustinMillerAutomotive you're right. I've seen them switched around many times. Some of the boards that I've worked have used npn for both high side and low side. But the connection are opposite

What is a computer discrete input or out put

[@JustinMillerAutomotive]

Discrete signals refer to digital signals that only occur only at specific voltage steps, such as 0 volts or 5 volts or 10 volts. This is different than an analog voltage signal, where the voltage can vary infinitely and does not necessarily land at specific points.

[@treasuretotrash2067]

You use a pnp transistor for high side switching, not an npn.

[@JustinMillerAutomotive]

You're right. I am sorry for the error. Thank you.
