Please answer: As you said you love to use PI-Filters for INPUT INITAIL Power FILTERING. As you said you will create another video on: What values of capacitors and inductor for GENERAL purpose 5V power supply given to microcontroller ? Please share the link of video if you was able to make on pi filer. PI- filter work better with ceramic capacitor or with electrolyte capacitor ? what combination should be used with inductor ? At one point 12.36 , you mentioned , use bigger value of C5, C6 of electrolyte capacitor at down side of inductor, otherwise pi-filter will not be effective. low value of c5, c6 will make decoupling capacitor in-effective?? Please create a video on this test. Second Question: How EMI/EMC is harmful to any controller board ? How it disturb the working of board ?

Fantastic practical review. And I red the article in your blog. Its fantastic to. Thankvyou for the effort to simplify that important matter.

You missed the gate charge is at 4.5V (NOT 10V), so it is NOT the sweet spot. But I get your logic, not goby the oopsie! :)

this is why china is getting ahead of you guys.

Nice video. I'll have to watch it again. Im currently doing exactly what you show not to do. 😅 its just temp. Im building my first drone and learning battery control. I cracked open a 5v 1amp cellphone battery bank, there is a board that steps up 3.7v to 5v that i need for my drone motors. I need 2amp, and im uncertain of what module to get for light weight battery control with 5v 2 amp step up. If you have suggestions. I appreciate your comments.

I have to disagree about the "two kinds of MOSFETs" You can certainly have high power logic level MOSFETs. An example that is not particularly new is the FDP8880. What makes a MOSFET logic level is a low threshold voltage. Particularly a MOSFET that will be essentially turned full on at or blow a Vgs of 5V. The FDP8880 has rds of only 14.5 mohm at 4.5V Vgs and can pass up to 54A, deal with 30V and dissipate 55W.

This is actually rather a good guide for designing a reliable product

It´s the first time I understand somebody talking about electronics (at least, electronics on this level). Very well explained...!!! I was such an idiot all those months trying to learn electronics: At very high frequencies, the turn-on/off-time really gets out of controll, proportionally, I was so blind and totally overlooked it...!!!

Nah, if the charger reduces charge current as the battery fills, the charger won't end up over charging the battery... The charger will just power the device once the charge current is reduced to the device load.

Awesome stuff

Very good information, thank you for sharing!

Fantastic Video, thank you! On a side note, it may be helpful to provide us with the libraries you are using. I had a hard time finding the voltage regulator symbol on the web, or maybe let us know we can use alternatives in case we cannot find the symbol online to add to our libraries

Is Matthew Miller your father?

Upspeak is hard for me to understand

Can you make 100W bidirectional DC DC boost converter from 7-60Vdc to 100-500Vdc which can be controlled by I2C using GAN fets?

how you chosen the current value to be 25 amps please explain

thanks

Great Video! Engagement.

Great Video! Engagement.

Great video! Engagement.

Good video. Engagement!

Thank you. Engagement!

Professor please help!! When I was looking for MJE13005 datasheet I found there are two parameters named as VceO(sus)=400VDc and other is Vce=700VDC, so what does these two means?? Now which one is to consider as max withstand voltage rating when choosing this bjt to switch inductive load like smps ?? Please help

Its a great video. Your content has more information as compared to others. I saw lot of videos on EMI/EMC from well know youtubers. Everyone is talking about , How to reduce EMI/EMC from PCB , so that it can pass a TEST. But NO ONE is discussing about : How to resolve PCB , which is not working properly due to 1. EMI/EMC from PCB. 2. due to power supply 3. EMI/EMC due to inductive load.

Seven 22uf ... Each input pin has two capacitor and close to pin ? or noise is first filtered through seven 22uf capacitor and then given to input pins????

I saw your video first time and you sound me quite knowledgeable. I have two questions: 1. 5V is given to microcontroller from external SMPS. Can TVS diode be used as filter to clean 5V DC ? Is it possible that 5V DC have disturbance or spike during switching of 220V AC inductive load ? 2. What other filter can be used to clean 5V DC going to microcontroller? 3. I mean TVS + reverse polarity protection diode + filter ???? to suppress side effects of inductive load switching.

good video. thank you!

he is just reading stuff, very bad explanation and talking style. Why are you not confident to talk facing camera all the time being a youtubeer?

I know this is a year old now, but just came across this today. With USB you always want the resistors to be placed close to the chip. Yes it is bi-directional and as a general rule, for bidirectional lines, you can place them in the middle. But on a long transmission line you actually what them at both ends of the line at each of the transmitter/receivers. Your typical USB link is a long transmission line, in fact you likely only have one end of the link on the board. The USB spec has taken this into account and specifies the resistors at both ends. Some chips integrate them, so you don't need to include them on-board in that case.

Love that ideal 🎉

That thumbnail is such a nice picture of a MOSFET.

Question do i have to add a TVS diode for each pin that i expose?

Thanks for a great video, 3 years down the road and its still very useful and insightful for folks entering the Li-Ion space.

How to measure a smd in a pcb

This is a great set of insights. It parallels what I've learned vicariously through a guy who does our boards on a Manncorp line. Lots and lots of tribal knowledge.

One user case you didnt cover: we have a need for rapid prototype iteration. I can get pcb fab and stencil from china in 6 days for cheap. Assembling that thing by hand with 300-600 placements is hell. All the CN benchtop machines are a mess. The hobbiest OpenPnP machines are scary and low quality feeder'd. Where are the other options?

You're such a good teacher.

Wow.. you make things so much easier to understand. You dont assume we know anything at all and its great. Everything you say if it isnt obvious, you breifly explain what you meant in laymans terms. Thank you!

I'm on a crusade to get tutorial creators to avoid inserting the severely distracting talking-head in their tutorials.

Nice video...i have a issue with 210khz failing CE...but that's on AC power line which carries like 80A AC current and has power line communication on it...

i slept in....sorry

So my application has a p type mosfet because i am controlling it from a current sinking device. I suppose i still need to worry about the max voltage between the drain and the source and the gate and the source? That sorta sucks

How about the DC bias of the C0G class 1 MLCC capacitors?

Mint!

Man I really appreciate that! In so many ways. Glad you're looking after your health 1st.

Thanks for this, it's exactly the level of detail I needed, and from your explanation I can appreciate when and why there are cases where far more detailed selection/calculations would be required. i suspect that for my purposes I'll probably never need more than these basic selection considerations and quick safe limit proximity checks.

Thank you!

A concise, to the point explanation in a language the 'mortal' being can understand without the 'gobbledygook' and 'dreaded' calculus. Great stuff, keep it up!

did u mean low esr cap?
