Temperature Switch IC regulates operation based on heat.
Press Release Summary:
Able to detect temperature over 40 to +120° range with accuracy of ±2.5°, S-5843A Series inverts output when temperature reaches detection temperature and restores output voltage when temperature drops to level of release temperature. Temperature sensor with negative temperature coefficient, reference voltage generation circuit, comparator, and delay circuit are integrated in one Pb-free package. Operating from 1.65 V supply, IC draws 4.5 µA typ due to CMOS configuration.
Original Press Release:
Temperature Switch IC S-5843A Series
The S-5843A Series is a temperature switch IC which detects the temperature with a temperature accuracy of ±2.5°. The output inverts when temperature reaches the detection temperature. This IC 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 small packages SNT-6A and SOT-23-5.
