ADM1033
Thermal Monitor and Fan
Speed (RPM) Controller
The ADM1033 is a one channel remote- and local-temperature
sensor and fan controller. The remote channel monitors the
temperature of the remote thermal diode, which may be discrete
2N3904/6s or may be located on a microprocessor die. The device also
monitors its own ambient temperature.
The ADM1033 can monitor and control the speed of cooling fan.
The user can program a target fan speed, or else use the look-up table
to input a temperature-to-fan speed profile. The look-up table can be
configured to run the fans at discrete speeds (discrete mode) or to ramp
the fan speed with temperature (linear mode).
The ADM1033 communicates over a 2-wire SMBus 2.0 interface.
An 8-level LOCATION input allows the user to choose between
SMBus 1.1 and SMBus 2.0. An ALERT
  output indicates error
conditions. The THERM
 I/O signals overtemperature as an output and
times THERM
 assertions as an input. Pin 8 can be configured as a
reference for the THERM
 (PROCHOT
) input.
