2.7. FAULT Output
The FAULT output (Si8517/8/9) guards against Si85xx
output signal errors caused by missing reset cycles.
FAULT is asserted when a measurement cycle exceeds
the internal watchdog timer times limit of t WD . FAULT
can be used to alert a local microcontroller or digital
power controller of a current sense failure or to initiate a
system shutdown. To detect faults, tie a 200 k ? resistor
from TRST/FAULT to VDD.

2.6. Leading Edge Noise Suppression
High-amplitude spikes on the leading edge of the
primary switching waveforms can cause the PWM latch
to be erroneously reset at the start of the switching cycle
when operating in current mode control. To prevent this
problem, leading edge blanking is commonly used to
disable the current comparator during the early portion
of the primary-side switching cycle. The Si85xx
eliminates leading-edge noise spikes by including them
in the signal integration. As shown in the output
waveform of Figure 8 (Si8502 waveform measured
directly on OUT pin with no external filter), noise present
in the input waveform is eliminated without the use of
blanking.
The Si85xx is a very robust current sensor. Its maximum
input current rate of change is limited to 1000 A/μs. The
maximum peak ac input current limit is 200 A. The
thermal limit or continuous dc current flow limit is 30 A.
Exceeding these limits may cause long-term reliability
issues. Refer to “AN329: Extending the Full-Scale
Range of the Si85xx” for more information.
