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
I²C interface compatible. The devices are specified over a temperature range of –40°C to +125°C. The
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.
