SM6611 series
Miniature High-Precision Temperature Switch IC
NIPPON PRECISION CIRCUITS INC.
OVERVIEW
The SM6611 series are temperature switch ICs that change state (invert) when the chip temperature exceeds a
preset temperature. The switches are designed with temperature hysteresis to prevent unstable output when the
temperature is in the vicinity of the preset temperature.
There are 6 output switching temperatures in the series, available in 2 output configurations, making the
SM6611 series devices ideal for a wide range of applications.
