    NCT475
    Industry Standard Digital
    Temperature Sensor in CSP
    Package with 2-wire
    Interface
    The NCT475 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 NCT475 is accomplished via the
    SMBus/I2C interface which is compatible with industry standard
    protocols. Through this interface the NCT475s 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 NCT475 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 NCT475 is available in a space saving 6 ball CSP package as
    NCT475A and NCT475B. NCT475B gives I2C address options of ...

The NCT475 is available in a space saving 6 ball CSP package as
NCT475A and NCT475B. NCT475B gives I2C address options of
0x48 and 0x4A while NCT475A gives address options of 0x49 and
0x4B. NCT475 is also fully register compatible with the NCT75,
LM75 and TMP75. www.onsemi.com
