NCT52

The NCT51/NCT52   are SOT23 temperature switches that require no external components and the design is facilitated with factoryprogrammed temperature thresholds. A choice of factorytrimmed 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 mA of current and operate over the entire 55°C to +125°C temperature range while offering accuracies of
0.5°C (typ) and
4°C (max).

The NCT51 has an open drain, active low output, meant for microprocessor reset control. The NCT52 has a CMOS, active high output designed to drive a logic level MOSFET to turn on a fan or heater element.The NCT51/NCT52 are aimed for hottemperature monitoring (+45°C to +115°C). These NCT51/NCT52  devices assert a logic signal when the temperature goes above the threshold.

The NCT51/NCT52  are offered in three standard temperature thresholds. Available in 5Pin SOT23A packages, these parts are ideal for applications requiring high integration, small size, low power and low installed cost.
