LM75 Digital Temperature Sensor and Thermal WATCHDOG with Two-Wire Interface January 2000 LM75 Digital Temperature Sensor and Thermal WATCHDOG™ with Two-Wire Interface General Description 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 bees active when the temperature exceeds a programmable limit. This pin can operate in either “parator” or “Interrupt” mode. The host can program both the temperature alarm threshold (TOS) and the temperature at which the alarm condition goes away...
