NCT51, NCT52 Ultra Small Temperature Switch with Pin-Selectable Hysteresis The NCT51 and NCT52 are SOT 23 temperature switches that require no external components and the design is facilitated with factory programmed temperature thresholds.
A choice of factory trimmed temperature trip points are available.
Pin selectable hysteresis of +2°C or +10°C allows flexibility to the design.
These parts typically consume only 17 µA of current and operate over the entire 5
