The S-5841 Series is a temperature switch IC which detects the temperature with a temperature accuracy of 2.5C. 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 A 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.
