Seiko Instruments Introduces World's Lowest Power Consumption Temperature Switch IC

TOKYO, June 15, 2011/PRNewswire-FirstCall/ --

    -S-5844 series temperature switch IC improves mobile device safety and
reliability-

    Seiko Instruments Inc. (SII) announced on June 15 the S-5844 series, the
world's lowest power consumption 180nA temperature switch IC. The series
features 1.65V low operating voltage in an ultra-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 S-5844 series temperature switch IC operates at the low supply
voltage of 1.65V with typical current consumption of 180nA extending battery
life and device operating time.

    The series utilizes a super-small HSNT-4(1010) package (1.0 x 1.0 x 0.4
mm), enabling high density mounting. 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, the S-5844 series allows for a wide range of applications.
