    MIC281 - Low-Cost IttyBitty? Thermal Sensor
    Docket ↓
    Low-Cost IttyBitty™ Thermal Sensor General Description Features 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.  Remote temperature measurement using embedded
    thermal diodes or commodity transistors  Accurate remote sensing: ±3°C max., 0°C to 100°C  Excellent noise rejection  I C and SMBus 2.0-compatible serial interface  SMBus timeout to prevent bus lockup 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.  Voltage tolerant I/Os  Low power shutdown mode  Failsafe response to diode faults  3.0V to 3.6V power supply range  Available in IttyBitty SOT23-6 package A 2-wire SMBus 2.0-compatible serial interface is provided
    for host communication. The clock and data pins are 5Vtolerant regardless of the value of VDD. 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. 2 Applications
