NCT75
Industry Standard Digital
Temperature Sensor with
2wire 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癈 to +125癈 temperature range.
Communication with the NCT75 is accomplished via the
SMBus/I
2
C 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.
