NCT214MT3R2G Thermal Management by ON Semiconductor

±1°C Temperature Monitor with Series Resistance Cancellation and Addressability


The NCT214 is a dual-channel digital thermometer and undertemperature/overtemperature alarm, intended for use in PCs and thermal management systems. It is register-compativle with the ADM1032 and ADT7461. A feature of the NCT214 is series resistance cancellation, where up to 1.5kΩ (typical) of resistance in series with the temperature monitoring diode can be automatically cancelled from the temperature result, allowing noise filtering. The NCT214 has a configurable /ALERT output and an extended, switchable temperature measurement range. The NCT214 can measure the temperature of a remote thermal diode accurate to ±1°C and the ambient temperature accurate to ±3°C. The temperature measurement range defaults to 0°C to +127°C, compatible with the ADM1032, but it can be switched to a wider measurement range of -64°C to +191°C. The NCT214 communicates over a 2-wire serial interface, compatible with system management bus (SMBus/I2C) standards. The NCT214 has two address pins which allow up to 9 NCT214s to be used on the same bus. An /ALERT output signals when the on-chip or remote temperature is out of range. The /THERM output is a comparator output that allows on/off control of a cooling fan. The /ALERT output can be reconfigured as a second /THERM output, if required.
