NCT275 Industry Standard Digital Temperature Sensor

Ball Name A2 Ball Function SDA Description SMBus/I2C Serial Biïdirectional Data Input/Output. Openïdrain pin; needs a pullïup resistor. A1 VDD Positive Supply Voltage, 3.0 V to 5.5 V. Bypass to ground with a 0.1mF bypass capacitor. B2 SCL Serial Clock Input. Openïdrain pin; needs a pullïup resis.

NCT275 Industry Standard Digital Temperature Sensor in CSP Package with 2-wire Interface The NCT275 is a twoïwire serially programmable temperature sensor with an overïtemperature/interrupt output pin to signal out of limit conditions. This is an openïdrain pin and can operate in either comparator or interrupt mode. Temperature measurements are converted into digital form using a high resolution (12 bit), sigmaïdelta, analogïtoïdigital converter (ADC). The device operates over the 55°C.
