Part Number: INA700

Hi team,

As below, IN+ is 12V

IN- is the load

the 3V3 is coming from IN+ which is stepping down from 12V

May I know if my load (IN-) has 12V or not when there is no 3V3 to the INA700?

Thanks

Hi Corry,

If your bus supply rail has 12V on it, then the load will also have 12V supply. Please note the Vs pin is supplied separately, it is not tied to the IN+ pin internally.

HI Mallika,

I mean the 12 V at the load still has 12V regardless to the VS pin, right?

Yes, that's right.
