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.

Micro8t

Communication with the NCT375 is accomplished via the

CASE 846A

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
