The S-5841 Series is a temperature switch IC. The S-5841 Series has a built-in IC temperature sensor with the accuracy of ±2.5°C and detects the temperature. This IC restores the output voltage when the temperature drops to the level of release temperature. The S-5841 operates at the lower power supply voltage of 2.2 V and its current consumption is 10 µA Typ. due to CMOS configuration. A temperature sensor with the negative temperature coefficient, a reference voltage generation circuit and a comparator are integrated on one chip, and enclosed into the small packages SNT-6A and SOT-23-5.
