Operation

2.3
Comparator mode
In Comparator mode, each time a temperature-to-digital (T-to-D) conversion occurs, the new
digital temperature is compared to the value stored in the T
OS
and T
HYS
registers. If a fault
tolerance number of consecutive temperature measurements are greater than the value
stored in the T
OS
register, the OS/INT output will be asserted.
For example, if the FT1 and FT0 Bits are equal to “10” (fault tolerance = 4), four consecutive
temperature measurements must exceed T
OS
to activate the OS/INT output. Once the
OS/INT output is active, it will remain active until the first time the measured temperature
drops below the temperature stored in the T
HYS
register, whereupon it will reset to its
inactive state.
Putting the device into Shutdown mode does not clear OS/INT in Comparator mode.
2.4
Interrupt mode
In Interrupt mode, the OS/INT output becomes active when the measured temperature
exceeds the T
OS
value a consecutive number of times as determined by the Fault Tolerance
bits (FT1, FT0) value in the Configuration register. Once activated, the OS/INT can only be
cleared by reading from any register (temperature, configuration, T
OS
, or T
HYS
) on the
device. Once the OS/INT has been deactivated, it will only be reactivated when the
measured temperature falls below the T
HYS
value a consecutive number of times equal to
the FT value. This mode is better suited for interrupt driven microprocessor based systems.
