onsemi NCT72
The NCT72 is a dual-channel digital thermometer and undertemperature/overtemperature alarm, intended for use in PCs and thermal management systems. It is pin and register compatible with the NCT1008 but the NCT72 allows the user to pull the ALERT pin to 1.8 V without increasing the device Idd. The NCT72 has a configurable ALERT output and an extended, switchable temperature measurement range.| Part No. | NCT72 |
