Description

General part information

SM72480 Series

The SM72480 is a low-voltage, precision, dual-output, low-power temperature switch and temperature sensor. The temperature trip point (TTRIP) is set at the factory to be 120°C. Built-in temperature hysteresis (THYST) keeps the output stable in an environment of temperature instability.

In normal operation the SM72480 temperature switch outputs assert when the die temperature exceeds TTRIP. The temperature switch outputs will reset when the temperature falls below a temperature equal to (TTRIP− THYST). The OVERTEMP digital output, is active-high with a push-pull structure, while theOVERTEMPdigital output, is active-low with an open-drain structure.

The analog output, VTEMP, delivers an analog output voltage with Negative Temperature Coefficient — NTC.
