7.1 Overview

The TMP464 device is a digital temperature sensor that combines a local temperature measurement channel and four remote-junction temperature measurement channels in a VQFN-16 package. The device has a two-wire-interface that is compatible with I2C or SMBus interfaces and includes four pin-programmable bus address options. The TMP464 is specified over a local device temperature range from –40°C to +125°C. The TMP464 device also contains multiple registers for programming and holding configuration settings, temperature limits, and temperature measurement results. The TMP464 pinout includes THERM and THERM2 outputs that signal overtemperature events based on the settings of temperature limit registers.
