MIC280
Precision IttyBitty™ Thermal Supervisor General Description Features 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

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.  Measures local and remote temperature
 Highly accurate remote sensing: ±1°C max., 60°C to
100°C
 Superior noise immunity for reduced temperature
guardbands
 9-bit to 12-bit temperature resolution for remote zone
 Fault queues to further reduce nuisance tripping …
