🔴Vlog#5 How does the DC-in and Charging circuit works on a laptop motherboard? - BQ24780S

This will help the beginners and those people who wants to learn and to have an idea on how does the DC-in and the standard Hybrid Power Boost (HPB) charging Circuit works to charge the battery and so on.. you will understand where and what voltage should you get on the specific points on the laptop motherboard DC-in and charging circuit section.. and if you want to get the animation file, you can join our discord server and get it there. I will put our Discord server Link down below so that you can get access on the file..

The clearest; most comprehensive; and conceptually well developed presentation on this topic I have ever seen !! Thanks for sharing !!

[@jetskyamorsolo5328]

Thank you for the informative video. Hope to see more of this video from you! More power to your channel

[@janmichaelbesinga3867]

Very comprehensive, accurate, and easy to understand! Waiting for the PWM explaination video 🤣👌🏻💯❤️

[@adelekebulejo5916]

Good explanation, I really appreciate all your effort on this. But PLS I NEED FOR SUPER IO Just like this animation thanks

[@vlatkosurlan545]

Very good explanation. I was logically expecting the mosfet to be turned on by something that was powered directly by the VIN from the DC jack but ChatGPT was trying to convince me that the BQ chip was powered by the B+ voltage which makes no sense.

Nice explaining man , you did a nice job better then i ever could i will use your clip a lot when i help someone .😊😉👍

Hi. Very very nice explanation. I got a good full explanayion. I know how the charging circuit work. But it was 50 persent. I was searching a long time,for a explanation like this. Its wonderful. Thsnk you master

Thank you for the support,.. if i remember it correctly you are our rizsha from the SIERA server right? 🙂

I have the a machine, with such charging ic, but laptop not charging, phase has 0.12 volts, what could be the failure

[@Manouchehrkhodadadegan]

Perfect explenetion

ACOK is not present, what is the reason? and what is the solution?

Thank you so much boss. This is what so many are hiding from us

[@georgethomas9422]

👍👍👍👍

[@alexanderinciong2450]

may follow up question ako sir fred bakit on some board there are 4 mosfet sa highside at lowside? ganda sana may part 6 yung sa PWM

[@sipansibabdreddknot5179]

yung yung isang klase ng charging architecture yung nvdc yung 20v or 5v i boost ng 2 unang mosfet sa coil then yung next 2 mosfet naman eh regulate papuntang battery na agad
