S-5841 Series www.sii-ic.com © Seiko Instruments Inc., 2007-2015 TEMPERATURE SWITCH IC (THERMOSTAT IC) Rev.2.2_00 The S-5841 Series is a temperature switch IC (thermostat IC) which detects the temperature with a temperature accuracy of ±2.5°C. The output inverts when temperature reaches the detection temperature. The S-5841 Series restores the output voltage when the temperature drops to the level of release temperature. The S-5841 Series 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, a comparator and a delay circuit are integrated on one chip, and enclosed into the packages SOT-23-5 and SNT-6A.
