INA226 Alert Pin Rating

S R
Prodigy 10 points

Please provide pin rating for the open-drain Alert Pin.

The datasheet lists 10mA current sink capability but not the maximum voltage.

The application diagram shows it pulled up to the supply pin but I want to pull it to a higher voltage.

Is this possible and what is the maximum voltage?

Thanks

    S R,

    For this device, the maximum pull-up voltage for the ALERT pin is 5.5V.  The supply can be lower, 2.7V for instance, and the pull-up can be 5.5V.  Beyond 5.5V, the behavior can be erratic, even producing low values, and sink hundreds of mA, and also irreparably damage the device.

    I hope this helps; please let me if I can be of further assistance.

    Regards,

    Jason Bridgmon
