The TMP709AIDBVT is a fully-integrated Resistor-programmable Temperature Switch with a temperature threshold that is set by just one external resistor within its entire operating range. The TMP709 provides an open-drain, active-low output. The device incorporates two temperature-dependent voltage references and one comparator. One voltage reference exhibits a positive temperature coefficient (tempco) and the other voltage reference exhibits a negative tempco. The temperature at which both voltage references are equal determines the temperature trip point.
