1 Introduction

The TMP4718 is a high-accuracy, low-power remote temperature sensor monitor with a built-in local temperature sensor. The remote temperature sensors are typically low-cost discrete NPN or PNP transistors, on-die transistors or diode structures that are an integral part of microprocessors, microcontrollers, and FPGAs. Temperature accuracy for the local and the remote temperature sensors is ±1°C. The two-wire serial interface accepts SMBus communication protocol. The module and GUI are designed to provide the user a quick setup to evaluate the system and register map. The EVM perforations allow the user to isolate and connect the temperature sensor, microcontroller, and remote BJT to external systems.
