File Size : 116 KB Manufacturer:JST Description:The LM77 is a digital temperature sensor and thermal win- dow comparator with an I2C™ Serial Bus interface. The window-comparator architecture of the LM77 eases the de- sign of temperature control systems conforming to the ACPI (Advanced Configuration and Power Interface) specification for personal computers. The open-drain Interrupt (INT) out- put becomes active whenever temperature goes outside a programmable window, while a separate Critical Tempera- ture 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. The host can program both the upper and lower limits of the window as well as the critical temperature limit. Program- mable hysterisis as well as a fault queue are available to minimize false tripping. Two pins (A0, A1) are available for address selection. The sensor powers up with default thresh- olds of 2˚C THYST, 10˚C TLOW, 64˚C THIGH, and 80˚C T_CRIT. The LM77s 3.0V to 5.5V supply voltage range, Serial Bus interface, 9-bit + sign output, and full-scale range of over 128˚C make it ideal for a wide range of applications. These include thermal management and protection applications in personal computers, electronic test equipment, office elec- tronics, automotive, and HVAC applications.
