TEMPERATURE SWITCH IC
S-5841 Series
The S-5841 Series is a temperature switch IC which detects the temperature
with a temperature accuracy of ±2.5°C. This IC restores the output voltage
when the temperature drops to the level of release temperature.
The S-5841 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 and a comparator are integrated on one chip, and
enclosed into the small packages SNT-6A and SOT-23-5.
