More Information

The LM92 is a digital temperature sensor and thermal window comparator with an I2C Serial Bus interface and an accuracy of ±0.33°C. The window-comparator architecture of the LM92 eases the design of temperature control systems. The open-drain Interrupt (INT) output becomes active whenever temperature goes outside a programmable window, while a separate Critical Temperature Alarm (T_CRIT_A) output becomes active when the temperature exceeds a programmable critical limit. The INT output can operate in either a comparator or event mode, while the T_CRIT_A output operates in comparator mode only.
