NCT375  
Industry Standard Digital  
Temperature Sensor with  
2‐wire Interface  
The NCT375 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 NCT375 is accomplished via the  
CASE 846A  
2
SMBus/I C interface. Three address selection pins, A2, A1 and A0,  
can be used to connect up to 8 NCT375s to a single bus. Through this  
interface the NCT375s 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 NCT375 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 NCT375 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 NCT75, LM75 and TCN75.
