3.3.5. Measurement Watchdog Timer and FAULT Output
A built-in watchdog timer disables measurement and holds OUT or OUT1 and OUT2 at their minimum values when
the time between integrator resets exceeds the FAULT Detect Time. The output signal from this watchdog is
available on the FAULT output pin (Si8517/8/9 only).
Figure 15 illustrates two means of entering a fault condition. Either fault condition 1 or 2 occurs when the reset
period exceeds the FAULT Detect Time, which ranges from 30 to 80 µs due process variations. The fault condition
ends when the next logic reset cycle begins.
