GENERAL 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.

    1 local and 2 remote temperature channels
    ±1°C accuracy on local and remote channels
    Automatic remote temperature channels, up to 1 kΩ
    Fast (up to 64 measurements per second)
    SMBus 2.0, 1.1, and 1.0 compliant
    SMBus address input/LOCATION input to UDID
    Programmable over-/undertemperature limits
    Programmable fault queue
    SMBusALERT output
    Fail-safe overtemperature comparator output
    Fan speed (RPM) controller
    Look-up table for temperature-to-fan-speed control
    Linear and discrete options for look-up table
    FAN_FAULToutput
    THERM input, used to time PROCHOT assertions
    REF input, used as reference for THERM (PROCHOT)
    3 V to 5.5 V supply
    Small 16-lead QSOP package

APPLICATIONS
    Desktop and notebook PCs
