The ADT7473 uses the 2-wire interface compatible with the SMBUS 2.0

specification. Using an analog to digital converter it measures three (3)
|

temperatures and two (2) voltages. It has three (3) 16-bit counters for
|
||||
temperatures and two (2) voltages. It has four (4) 16-bit counters for
|
||||
measuring fan speed. There are three (3) PWM outputs that can be used
|
||||
to control fan speed.
|
||||
|

A sophisticated control system for the PWM outputs is designed into the

LM85 that allows fan speed to be adjusted automatically based on any of the

ADT7473 that allows fan speed to be adjusted automatically based on any of the

three temperature sensors. Each PWM output is individually adjustable and

programmable. Once configured, the ADT7473 will adjust the PWM outputs in
|
||||
response to the measured temperatures without further host intervention.

The Analog Devices datasheet is very detailed and describes a procedure for

determining an optimal configuration for the automatic PWM control.

Hardware Configurations
|
||||
-----------------------
|
||||
|
||||
The ADT7473 chips have an optional SMBALERT output that can be used to
|
||||
signal the chipset in case a limit is exceeded or the temperature sensors
|
||||
fail. Individual sensor interrupts can be masked so they won't trigger
|
||||
SMBALERT. The SMBALERT output if configured replaces the PWM2 function.
