    Hi,

    The output of the TMP300 is normally high and is pulled low when the temperature threshold is tripped. You can see this by observing the open-drain output, which uses a pull-up resistor, which pulls the OUT pin high when the chip is floating (when the switch is not tripped).

    Thanks for the question!
