TMP275 ALERT sink current capabilities

Jake

The datasheet does not specify the max sink/source current capabilities of the ALERT pin.

I would like to connect a LED to that pin, sinking 5mA. Can I do that for a few seconds?

Jake,

I am currently looking into this and will get back to you shorty.

Jake,

For the Alert pin IOL = 4mA. I recommend using a 1k ohm pull up resistor on the Alert pin and placing the LED from the Alert pin to ground.

Chris, thank you for the information.
