7 Detailed Description

7.1 Overview

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

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 and TMP101 devices.

The temperature sensor in the TMP100 and TMP101 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 or TMP101 is directly connected to the

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