Precision IttyBitty™ Thermal Supervisor

REV. 11/04

General Description

Features

TheMIC280isadigitalthermalsupervisorcapableofmeasur-

ing its own internal temperature and that of a remote PN junc-

tion. The remote junction may be an inexpensive commodity

transistor, e.g., 2N3906, or an embedded thermal diode such

as found in Intel Pentium* II/III/IV CPUs,AMDAthlon* CPUs,

and Xilinx Virtex* FPGA's. A 2-wire SMBus* 2.0 compatible

serial interface is provided for host communication. Remote

temperature is measured with ±1°C accuracy and 9-bit to

12-bitresolution(programmable).Independenthigh,low,and

over-temperature thresholds are provided for each zone.

• Measures local and remote temperature

• Highly accurate remote sensing

±1°C max., 60°C to 100°C

• Superior noise immunity for reduced temperature guard-

bands

• 9-bit to 12-bit temperature resolution for remote zone

• Fault queues to further reduce nuisance tripping

• Programmable high, low, and over-temperature thresh-

olds for each zone

• SMBus 2 compatible serial interface including device

timeout to prevent bus lockup

• Voltage tolerant I/O’s

• Open-drain interrupt output pin - supports SMBus Alert

Response Address protocol

• Low power shutdown mode

• Locking of critical functions to insure failsafe operation

• Failsafe response to diode faults

• Enables ACPI compliant thermal management

• 3.0V to 3.6V power supply range

• IttyBitty™ SOT23-6 package

insure failsafe operation. The clock, data, and interrupt pins

are 5V-tolerant regardless of the value of V . They will not

clamp the bus lines low even if the device is powered down.

Superior accuracy, failsafe operation, and small size make

the MIC280 an excellent choice for the most demanding

thermal management applications.

Applications

• Desktop, server and notebook computers

• Printers and copiers
