TEMPERATURE SWITCH IC (THERMOSTAT IC)
Rev.2.2
_02
The S-5841 Series is a temperature switch IC (thermostat IC) which detects the temperature with a temperature accuracy of
2.5C.
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
A
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.
