7 Detailed Description

7.1 Overview

The TMP175-Q1 and TMP75-Q1 devices are digital temperature sensors that are optimal for thermal

management and thermal protection applications. The TMP175-Q1 and TMP75-Q1 are two-wire, SMBus, and

Functional Block Diagram section shows the internal block diagram of the TMP175-Q1 and TMP75-Q1 devices.

The temperature sensor in the TMP175-Q1 and TMP75-Q1 devices is the chip itself. Thermal paths run through

the package leads as well as the plastic package. The package leads provide the primary thermal path because

of the lower thermal resistance of the metal.
