Description

The ADM1034 is a dual-channel remote- and local-temperature sensor and fan controller. The remote channels monitor the  temperature of two remote thermal diodes, which may be  discrete 2N3904/6s or may be located on a microprocessor die.  The device also monitors its own ambient temperature.

The ADM1034 can monitor and control the speed of two cooling fans. 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).
