S-5843A Series www.sii-ic.com © Seiko Instruments Inc., 2009-2015 TEMPERATURE SWITCH IC (THERMOSTAT IC) Rev.2.2_00 The S-5843A 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-5843A Series restores the output voltage when the temperature drops to the level of release temperature. The S-5843A Series operates at the lower power supply voltage of 1.65 V and its current consumption is 4.5 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.
