TEMPERATURE SWITCH IC (THERMOSTAT IC)
© SII Semiconductor Corporation, 2009-2015
Rev.2.2_01
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.
