Tổng Quan Sản Phẩm
NCT75DR2G is an industry standard digital temperature sensor with 2‐wire interface. It is a two-wire serially programmable temperature sensor with an over temperature/interrupt output pin to signal out of limit conditions. This is an open-drain pin and can operate in either comparator or interrupt mode. Communication with the NCT75 is accomplished via the SMBus/I2C interface. Three address selection pins, A2, A1 and A0, can be used to connect up to 8 NCT75s to a single bus. Through this interface the NCT75s internal registers may be accessed. These registers allow the user to read the current temperature, change the configuration settings and adjust the temperature limits. Typical applications include computer thermal monitoring, thermal protection, isolated sensors, battery management, office electronics, electronic test equipment, thermostat controls, system thermal management.
