Operation

Interrupt mode
In Interrupt mode, the OS/INT output first becomes active when the measured temperature
exceeds the T
OS
value a consecutive number of times equal to the FT value in the
Configuration register. Once activated, the OS/INT can only be cleared by either putting the
STDS75 into shutdown mode or 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.
Figure 5
illustrates typical OS output temperature
response for STDS75 configured to have a fault tolerance of 2. The interrupt/clear process
is cyclical between T
OS
and T
HYS
.

The STDS75 is configured to have a fault tolerance of 2 in this example.
This assumes that a READ has occurred.
