Nice👌. Informative video. Sir one request to you that make a detailed video on microcontroller ics used in various induction cook tops. It will be helpful to many technicians.🙏
Thanx for sharing sir, i have washing machine and it have ka75450 ic and output is fluctuation problem whats the problem? Reset pin how it work? Can i apply 5volt to reset pin from output power supply of jumper to pin 1 to pin 3 it work?
It's intended to reset mcu when it drops bellow certain treshold voltage like bellow 4.7V. That means, reset pin is in normal mcu operation held on high logic voltage, 5V. If it fluctuates, it prevents mcu from normal operation.
Good opportunity to point out that datasheets can't always be trusted! The circuit diagram on the front page has the op-amp inputs marked incorrectly. As shown the output will remain high until the input voltage goes past the reference voltage, then switch low!
Hello Sir, I am troubleshooting a 12v SMPS. it's similar to one of the SMPS troubleshooting video you created. Video # 749.. The DC voltage after bridge rectifier isn't coming up. I checked the 2 capacitors and accross polarity voltage are fluctuating. in reverse polarity the voltage is stable.. The two MOSFET aren't shorted either.. Kya kar sakte hai? Kya usme jo bade capacitors hai, unko hata ke power supply deke voltage check kar sakte hai kya on mosfet if voltage are coming or not. Removing the capacitors and powering on will damage other components?
Thank you for sharing. Have a good day.
thanks a lot dear friend. have a blessed day
Great Voltage detector IC KA75330 Video!
Beautifully Explained. This is deep knowledge.
it is my pleasure
Gracias por enseñar , un saludo grande desde ARGENTINA
Thanks for sharing and explained very well🎉🎉🎉
it is my pleasure
Always a learning day whenever you post a video. Thank you so much.
it is my pleasure

Teşekkürler hocam. Hayırlı cumalar.👍
Very informative information. Please sir explain how to programing MCU.
Really nice sir. 🎉
best regards

Great Videos. Thank you.
Its informative for us but my prediction's is there is another video about entire card so we are waiting
Thank you sir !!! ❤
Sir what kind of magnifing instrument you are using? many many thanks for your valuable information
it is ANDONSTAR AD407 Pro digital microscope
@@HaseebElectronics Ok sir thankyou so much

@@SanelKeys which one will be problem ic or mcu How can I learn which one is faulty? When i remove ic reset pin of mcu continue to flactuat
Nice Sir 👌👍

Your voice is very low.
Please loudly
i am sorry for that. i am trying to fix the audio issues.
