Tool/software:
Hello team,
Customer would like to implement the comparator by TL431.
question 1: What's the voltage stress of the REF pin?
2. When VIN > 2.5V, the VKA is conducting about 2V. I don't the see the datasheet E/C table has addressed the "2V". thanks.
Regards
Brian

Hi Brian,
This information can be found in the "Using the TL431 for Undervoltage and Overvoltage Detection" app note https://www.ti.com/lit/an/slva987a/slva987a.pdf?ts=1725482901520&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FTL431.
1. For question one refer to figure 4
2. For question 2 refer to figure 8
Thanks,
Joshua
For the question 1,
It doesn't describe the voltage stress on the VREF pin.
Or does it have series clamping diodes as below diagram so that it's following the VKA?
