Working Principles

The MAX6639ATE+T is a temperature sensor IC that utilizes an internal bandgap reference and a temperature-to-digital converter to accurately measure temperature. It converts the analog temperature signal into a digital value, which can be accessed through the I²C interface. The device also features programmable temperature limits, allowing users to set thresholds for triggering an alert output. In case of excessive temperature, the overtemperature shutdown input can be used to protect the system.
