Part Number: TL431
Hi,
I wanted to know if TL431 can be used for voltage sensing along with Opto coupler or not. Image of schematic and LTSpice model is attached for reference.
The input voltage i want to sense increases above 36V which is rating of Cathode to anode.
When Input votlage crosses 36V the Zener diode clamps. If i limit the current through zener(Cathode) can i use the same circuit for votlage sense and monitoring of OV
?
