The is a high-accuracy Temperature Sensor with adjustable over-temperature and under-temperature thresholds and open drain alert outputs. It converts the temperature of an external diode sensor or its own die temperature to an analogue output voltage while rejecting errors due to noise and series resistance. The measured temperature is compared against upper and lower limits set with resistive dividers. If a threshold is exceeded, the device communicates an alert by pulling low the correspondent open drain logic output. The device gives ±1°C accurate temperature results using commonly available NPN or PNP transistors or temperature diodes built into modern digital devices. A 1.8V reference output simplifies threshold programming and can be used as an ADC reference input.
