Dear expert,

My customer is looking for a TL431 as below, another pin is connect to cathode of photocoupler diode in actual application. Do we have device like that? I'm checking with customer why they need that. Thanks for your support.

  • Hi Minqi,

    We do not have a TL431 with the power supply being separated.

    Is this for a comparator application for overvoltage/undervoltage?

    If that is the case I will promote our open drain supervisors such as TPS3808 or TPS3890. I feel this will meet your application needs.
