a tested parameter in production. Switchpoint air gap generally drifts downward as temperature increases.

ATS636LSE
The switchpoint will vary over temperature. A sufficient margin obtained through customer testing is required to guarantee functionality over
The switchpoint will vary over temperature, proportionally to the programmed air gap. This parameter is based on characterization data and is not
