Temp Sensor Digital Serial (2-Wire) 8-Pin Micro T/R

The NCT175 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 Deg C to +125 Deg C temperature range. Communication with the NCT175 is accomplished via the SMBus/I2C interface. Three address selection pins, A2, A1 and A0, can be used to connect up to 8 NCT175s to a single bus. Through this interface the NCT175s 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 NCT175 has a wide supply voltage range of 3.0 V to 5.5 V. The average supply current is 575 A at 3.3 V. It also offers a shutdown mode to conserve power. The typical shutdown current is 3 A. The NCT175 is available in 8-lead Micro8 and is also fully pin and register compatible with the NCT75, LM75 and TCN75.
