onsemi NCT52
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 hot–temperature monitoring (+45°C to +115°C). These devices assert a logic signal when the temperature goes above the threshold.| Part No. | NCT52 |
