8 Detailed Description

8.1 Overview

The TMP100-Q1 and TMP101-Q1 devices are digital temperature sensors optimal for thermal management and

interface-compatible. These devices are specified over a operating temperature range of

−55°C to 125°C. The

Functional Block Diagram section shows the internal block diagrams of the TMP100-Q1 and TMP101-Q1

devices.

The temperature sensor in the TMP100-Q1 and TMP101-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. The GND pin of the TMP100-Q1 or TMP101-Q1 is directly

connected to the metal lead frame, and is the best choice for thermal input.
