Low-Cost IttyBitty Thermal Sensor IttyBitty
REV 11/04
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* II/III/IV CPUs, AMD Athlon* CPUs, and Xilinx
Virtex* FPGAs.
The MIC281 is 100% software and hardware backward com-
patible 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 man-
agement applications.
