_01
The S-5844A 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-5844A Series restores the output
voltage when the temperature drops to the level of release temperature.
The S-5844A Series operates at the lower power supply voltage of 1.65 V and its current consumption is 0.18
μA
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 packages SOT-23-5 and SNT-4A, and the super-small package HSNT-4 (1010).
