9 Detailed Description

9.1 Overview

The TMP1075 device is a digital temperature sensor that is optimal for thermal management and thermal

protection applications. The TMP1075 is a SMBus and is I2C interface-compatible. It is also capable of

coexisting in an I3C bus when in Mixed Fast Mode. The TMP1075 non-N orderables are specified over a

temperature range of −55°C to +125°C and the TMP1075N orderable is specified over the −40°C to +125°C

temperature range. The Figure 9-1 section shows an internal block diagram of TMP1075 device.

The temperature sensor thermal path runs through the package leads as well as the plastic package. The leads

provide the primary thermal path due to the lower thermal resistance of the metal.
