ADT7481
Dual Channel Temperature
Sensor and Overtemperature
Alarm
The ADT7481 is a 3-channel digital thermometer and under/ over
temperature alarm, intended for use in PCs and thermal management
systems. It can measure its own ambient temperature or the
temperature of two remote thermal diodes. These thermal diodes can
be located in a CPU or GPU, or they can be discrete diode connected
transistors. The ambient temperature, or the temperature of the remote
thermal diode, can be accurately measured to ?癈. The temperature
measurement range defaults to 0癈 to +127癈, compatible with
ADM1032, but can be switched to a wider measurement range from
64癈 to +191癈.
The ADT7481 communicates over a 2-wire serial interface
compatible with System Management Bus (SMBus) standards. The
SMBus address of the ADT7481 is 0x4C. An ADT74811 with an
SMBus address of 0x4B is also available.
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, for example, on/off control of a cooling fan. The
ALERT
output can be reconfigured as a second THERM
output if
required.
