    NCT75
    Industry Standard Digital
    Temperature Sensor with
    2‐wire Interface
    The NCT75 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. Temperature measurements are
    converted into digital form using a high resolution (12 bit),
    sigma-delta, analog-to-digital converter (ADC). The device operates
    over the –55°C to +125°C temperature range.
    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.
    The NCT75 has a wide supply voltage range of 3.0 V to 5.5 V. The
    average supply current is 575 mA at 3.3 V. It also offers a shutdown
    mode to conserve power. The typical shutdown current is 3 mA.
    The NCT75 is available in three, space saving packages – 8-lead
    DFN, 8-lead Micro8t and 8-lead SOIC and is also fully pin and
    register compatible with the LM75 and TCN75. http://onsemi.com DFN8 ...
