Slave Address
The MIC281 will only respond to its own unique slave ad-
dress. A match between the MIC281’s address and the
address specified in the serial bit stream must be made to
initiate communication. The MIC281’s slave address is fixed
at the time of manufacture. Eight different slave addresses
are available as determined by the part number. See Table
2 below and the Ordering Information table.

Temperature Data Format
The least-significant bit of the temperature register represents
one degree Centigrade. The values are in a two’s comple-
ment format, wherein the most significant bit (D7) represents
the sign: zero for positive temperatures and one for negative
temperatures. Table 3 shows examples of the data format
used by the MIC281 for temperatures.

Diode Faults
The MIC281 is designed to respond in a failsafe manner to
diode faults. If an internal or external fault occurs in the tem-
perature sensing circuitry, such as T1 being open or shorted
to V
DD
or GND, the temperature result will be reported as the
maximum full-scale value, +127°C. Note that diode faults will
not be detected until the first A/D conversion cycle is completed
following power-up or exiting shutdown mode.
Shutdown Mode
Setting the shutdown bit in the configuration register will
cause the MIC281 to cease operation. The A/D converter will
stop and power consumption will drop to the I
SHDN
level. No
registers will be affected by entering shutdown mode. The
last temperature reading will persist in the TEMP register.
