FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
The ADM1027 dBCOOL controller is a complete systems
monitor and multiple PWM fan controller for noise sensitive
applications requiring active system cooling. It can monitor
12 V, 5 V, 2.5 V CPU supply voltage, plus its own supply volt-
age. It can monitor the temperature of up to two remote sensor
diodes, plus its own internal temperature. It can measure and
control the speed of up to four fans so that they operate at the
lowest possible speed for minimum acoustic noise. The auto-
matic fan speed control loop optimizes fan speed for a given
temperature. Once the control loop parameters are programmed,
the ADM1027 can vary fan speed without CPU intervention.
