LM75 Digital Temperature Sensor and Thermal WATCHDOG

The LM75 is a temperature sensor, Delta-Sigma analog-to-digital converter, and digital over-temperature detector with I2C ® interface. The host can query the LM75 at any time to read temperature. The open-drain Overtemperature Shutdown (O.S.) output becomes active when the temperature exceeds a prog.
