摘要：

The features of a general-purpose smoke-detector IC make it an ideal temperature sensor alarm. The device includes its own voltage reference, a low-battery alarm, and a high-current driver. It also has very low current drain. The chip's comparator compares the voltage output of a sensor with the chip's own reference and triggers an alarm when the sensor's temperature rises above a preset level.
