TL431 Under-Voltage, Over-Voltage Detection 

I have these parts! (I see a nice evening coming up tonight at the bench!) Thanks Lewis!

Thank you for the efforts and valuable information

The 12Vbatter charger circuit uses a TL431 voltage detector and a TL431 constant current source. RU-vid video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-k1TOiKuBBG8.html www.bristolwatch.com/ccs/tl431_ccs4.htm TL431, LM317 Battery Charger Circuits Schematics

Thanks for sharing your knowledge. I hope you can explain BAV99 🙏🏽 Thanks you in advance!!

Fabulous

Good young man

🇨🇱👍

wtf happened to your audio ?! all on one side is so f'ed up
