Temperature Switch IC to keep devices
within a normal operating temp range
Seiko Instruments Inc. has announced S-5844 series, the
180nA temperature switch IC. The series features low operating
voltage of 1.65V in a small 1.0 x 1.0 mm package operating
over a wide temperature range from -40 to +125 degrees C.
The new temperature switch ICs have been optimized for use
in smart phones, cellular phones, notebook PCs, tablet PCs,
and other battery-operated portable device designs.
Temperature switch ICs are used to monitor temperature
to keep devices functioning within a normal operating temperature
range. The mobile/portable device market has been growing
rapidly. The demand for additional functionality and higher
processing speeds has increased heat generation. In addition
to high-density mounting and long battery life, these advanced
devices require heat management to protect against malfunction.
The S-5844 series temperature switch IC detects the specified
temperature and protects the device from heat generation
by inverting its output when the temperature threshold is
reached. The output voltage is restored when the temperature
drops to the specified release temperature. This enables
the device to avoid temperatures above its design limits,
improving safety and efficiency while reducing total design
cost.
The SNT-4A package (1.2 x 1.6 x 0.5 mm) is also available.
With a wide temperature range of -40 degrees C to +125 degrees
C.
