Overview
MIC280 Precision IttyBitty™ Thermal Supervisor General Description The MIC280 is a digital thermal supervisor capable of measuring its own internal temperature and that of a remote PN junction.
The remote junction may be an inexpensive commodity transistor—e.
g.
, 2N3906—or an embedded thermal diode such as those found in Intel Pentium® II/III/IV CPUs, AMD Athlon® CPUs, and Xilinx Virtex® FPGAs.
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-bit resolution (programmable).
Independent high, low, and overtemperature thresholds are provided for each zone.
The advanced integrating A/D converter and analog frontend reduce errors due to noise for maximum accuracy and minimum 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 ensure failsafe operation.
