How and why to replace discrete MOSFETs with load switches

[@Jerzy-wedrowiec]

The video is very good and useful. But! Didn't you mix up the arrows on all the transistors? The P channel transistor has an arrow outward and the N channel transistor has an arrow inward. It’s strange that in 7 years no one noticed this.

I am now a little more enlightened, thank you.

I liked this presentation. I learned a few things, and the newer TPS22975 part is just 16 cents qty 1, too! What’s not to like?

Audio says 47uf, slide shows 4.7uf, both can't be right..... (8:28) Now how do I switch 7a 90vdc on the high side with a 3.3v IO pin.....

what is goodfor low value voltages ?

[@walterbunn280]

Ehhh... Honestly, it depends on application of that low voltage value. The entire premiss of this video is discussing the over current situation that occurs when you first turn something on, or just after your batteries go dead. Jfet's handle those types of low voltage, high current situations better than MOSFETS. The vid didn't make that crystal clear.

Texas the world's best

EHhh.... This is really just a video on using Jfets... but you do not discuss why that's important/desirable. Honestly, i actually thought this was a video on how to jam mechanical relays into a design to ensure product failure over time. Luckily, it's not that, but the idea that MOSFETs are always the best option is pretty pervasive. It'd be helpful if you either spent a bit more time highlighting the weaknesses of the MOSFET or the Strength of the JFET. I personally prefer using JFETs for making my own discrete voltage and current regulating topologies. Depending on application, making your own can be cheaper, and it's definitely more robust, regardless of application.

Well, if you know the answer and do your own regulators, don't wait for others and and do a video yourself
