NCT275: Industry Standard Digital Temperature Sensor in CSP package with 2-wire interface
The NCT275 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 NCT275 is accomplished via the SMBus/I2C interface which is compatible with industry standard protocols. Through this interface the NCT275s 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 NCT275 has a wide supply voltage range of 3.0 V to 5.5 V. The average supply current is 575 μA at 3.3 V. It also offers a shutdown mode to conserve power. The typical shutdown current is 3 μA.
The NCT275 is available in a space saving 6 ball CSP package as NCT275A and NCT275B. NCT275B gives I2C address options of 0x48 and 0x4A while NCT275A gives address options of 0x49 and 0x4B. NCT275 is also fully register compatible with the NCT75, LM75 and TMP75
