ISO7331FC: Operation

Part Number: ISO7331FC

About ISO7331F-Q1,this device needs 2 VCCs,VCC1 and VCC2.

If VCC1 doesn't input,how does this device works?Just we can't get output?

  • Hi,

    Welcome to TI E2E Forum and thank you for showing interest in device ISO7331FC.

    You can find the function table of ISO7331FC in the datasheet section 8.4 on page 16, I am also copying it below for your reference.

    From the above table, you can notice that the output goes to default / failsafe state. For device ISO7331FC, the default state is LOW and hence the output will become LOW when input supply is turned off. Let me know if you have any other questions, thank you.
