TABLE VIII. Fault Settings of the TMP122 and TMP124.
THERMOSTAT MODE (TM1/TM0)
The Thermostat Mode bits of the TMP122/TMP124 indicate to
the device whether to operate in Comparator Mode, Interrupt
Mode or Interrupt Comparator Mode. For more information on
Comparator and Interrupt Mode, see text HIGH and LOW limit
registers. The bit assignments for thermostat mode are
described in Table VII. Power on default is comparator mode.
POLARITY (POL)
The Polarity Bit of the TMP122/TMP124 adjusts the polarity
of the ALERT pin output. By default, POL = 0 and the ALERT
pin will be active LOW, as shown in Figure 8. For POL = 1
the ALERT Pin will be active HIGH, and the state of the
ALERT Pin is inverted.
FAULT QUEUE (F1/F0)
A fault condition occurs when the measured temperature
exceeds the limits set in the THIGH and TLOW registers. The
Fault Queue is provided to prevent a false alert due to
environmental noise and requires consecutive fault mea-
surements to trigger the alert function of the TMP122/TMP124.
Table VIII defines the number of consecutive faults required
to trigger a consecutive alert condition. Power-on default for
F1/F0 is 0/0.
HIGH AND LOW LIMIT REGISTERS
In Comparator Mode (TM1/TM0 = 0/0), the ALERT Pin of the
TMP122/TMP124 becomes active when the temperature
equals or exceeds the value in THIGH and generates a
consecutive number of faults according to fault bits F1 and
F0. The ALERT pin will remain active until the temperature
falls below the indicated TLOW value for the same number of
faults.
In Interrupt Mode (TM1/TM0 = 0/1) the ALERT pin becomes
active when the temperature equals or exceeds THIGH for a
consecutive number of fault conditions. The ALERT pin
remains active until a read operation of any register occurs.
The ALERT pin will also be cleared if the device is placed in
Shutdown Mode. Once the ALERT pin is cleared, it will only
become active again by the temperature falling below TLOW.
When the temperature falls below TLOW, the ALERT pin
becomes active and remains active until cleared by a read
operation of any register. Once the ALERT pin is cleared, the
above cycle will repeat with the ALERT pin becoming active
when the temperature equals or exceeds THIGH.
In Interrupt/Comparator Mode (TM1/TM0 = 1/0), the ALERT
Pin of the TMP122/TMP124 becomes active when the tem-
perature equals or exceeds the value in THIGH and generates
a consecutive number of faults according to fault bits F1 and
F0. The ALERT pin will remain active until the temperature
falls below the indicated TLOW value for the same number of
faults and a communication with the device has occurred
after that point.
Operational modes are represented in Figure 8. Tables IX
and X describe the format for the THIGH and TLOW registers.
Power-up reset values for THIGH and TLOW are: THIGH = 80°C
and TLOW = 75°C. The format of the data for THIGH and TLOW
is the same as for the Temperature Register.
All 13 bits for the Temperature, THIGH, and TLOW registers are
used in the comparisons for the ALERT function for all con-
verter resolutions. The three LSBs in THIGH and TLOW can
affect the ALERT output even if the converter is configured for
9-bit resolution.
