SM6611 series

NIPPON PRECISION CIRCUITS INC.

Miniature High-Precision Temperature Switch IC

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.
