ON Semiconductor NCT75 is a two-wire programmable Temperature Sensor. Internal registers are accessed via the SMBus/I²C interface, allowing for current temperature reading, changes to configuration settings, and adjustment to temperature limits. An open-drain over-temperature/interrupt output pin, operated in either comparator or interrupt mode, signals out-of-limit conditions. NCT75 features a high resolution 12-bit analog-to-digital converter and a shut-down mode to conserve power.
