Revision 2.0
General Description
The MIC281 is a digital thermal sensor capable of
measuring the temperature of a remote PN junction. It is
optimized for applications favoring low cost and small size.
The remote junction may be an inexpensive commodity
transistor, e.g., 2N3906, or an embedded thermal diode
such as found in Intel Pentium
?/DIV>
II/III/IV CPUs, AMD
Athlon
?/DIV>
CPUs, and Xilinx Virtex
?/DIV>
FPGAs.
The MIC281 is 100% software and hardware backward
compatible with the MIC280 and features the same
industry-leading noise performance and small size. The
advanced integrating A/D converter and analog front-end
reduce errors due to noise for maximum accuracy and
minimum guardbanding.
A 2-wire SMBus 2.0-compatible serial interface is provided
for host communication. The clock and data 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 performance, low power, and small size make the
MIC281 an excellent choice for cost-sensitive thermal
management applications.
