NCT214

+15C Temperature Monitor

with Series Resistance

Cancellation

The NCT214 is a dual-channel digital thermometer and

undertemperature/overtemperature alarm, intended for use in PCs and

thermal management systems. It is register-compatible with the

ADM1032 and ADT7461. A feature of the NCT214 is series resistance

cancellation, where up to 1.5 kW (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.

WDFN10

CASE 522AA

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.

ALERT/THERM2

GND

The NCT214 communicates over a 2-wire serial interface,

compatible with system management bus (SMBus/I C) standards. The

NCT214 has two address pins which allow up to 9 NCT214s to be used

on the same bus.

(Top View)

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.
