ADT7482

Dual Channel Temperature

Sensor and Overtemperature

Alarm

The ADT7482 is a three-channel digital thermometer and

under/overtemperature alarm for PCs and thermal management

systems. It can measure the temperature in two remote locations, such

as in the remote thermal diode in a CPU or GPU, or using a discrete

diode connected transistor. This device also measures its own ambient

temperature.

One feature of the ADT7482 is series resistance cancellation where

up to 1.5 kW (typical) of resistance in series with each of the

temperature monitoring diodes can be automatically cancelled from

the temperature result, allowing noise filtering. The temperature of the

remote thermal diodes and ambient temperature can be measured

accurate to 1C. The temperature measurement range, which defaults

to 0C to 127C, can be switched to a wider measurement range of

from −55C to +150C.

The ADT7482 communicates over a 2-wire serial interface

compatible with System Management Bus (SMBus) standards. The

default address of the ADT7482 is 0x4C. An ALERT output signals

when the on-chip or remote temperature is outside the programmed

limits. 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.
