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 ?癈. The temperature measurement range, which defaults
to 0癈 to 127癈, can be switched to a wider measurement range of
from 55癈 to +150癈.
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.
