Update
The ATS665 incorporates an algorithm that continuously moni-
tors the system and updates the switching thresholds accordingly.
The switchpoint for each edge is determined by the previous
two edges. Since variations are tracked in real time, the IC has

high immunity to target run-out and retains excellent accuracy
and functionality in the presence of both run-out and transient
mechanical events. The figures below show how the IC uses his-
torical data to provide the switching threshold for a given edge.
