Precision IttyBitty" Thermal Supervisor
REV. 11/04
General Description
The MIC280 is a digital thermal supervisor capable of measur-
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, AMD Athlon* 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 ?癈 accuracy and 9-bit to
12-bit resolution (programmable). Independent high, low, and
over-temperature thresholds are provided for each zone.
The advanced integrating A/D converter and analog front-end
reduce errors due to noise for maximum accuracy and mini-
mum guardbanding. The interrupt output signals temperature
events to the host, including data-ready and diode faults.
Critical device settings can be locked to prevent changes and
insure failsafe operation. The clock, data, and interrupt pins
are 5V-tolerant regardless of the value of V
DD
. 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.
