Application information
The sensitivity depends on the track width and distance, as shown in figure 11.
The maximum current that can be safely applied continuously is determined by the temperature rise of the track.
The use of a track with varying width gives the best combination of sensitivity and track temperature rise.
The following paragraphs show optimized track shapes for bottom and top side tracks.
they are only examples and there could be many others depending on the application requirements.
