GENERAL DESCRIPTION
The ADM1033 is a remote and local temperature sensor and fan controller. Its remote channel accurately monitors the temperature of a remote thermal diode, which can be a discrete 2N3904/6 or located on a microprocessor die. The device can monitor its own ambient temperature as well.

FEATURES
    1 local and 1 remote temperature channel
    ±1.5°C accuracy on local and remote channels
    Automatic series resistance cancellation on remote
    Temperature channels > 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_FAULT output
    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
    Embedded systems
    Telecommunications equipment
