onsemi NCT51
The NCT51 and NCT52 are SOT–23 temperature switches that require no external components and the design is facilitated with factory–programmed temperature thresholds. These parts typically consume only 17 µA 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.- Min Voltage : 2.7V
- Max Voltage : 5.5V
- Max Operating Temp : 125°C
- Min Operating Temp : -55°C
