Application Information

PCB Layout Recommendations

The location and circuit board layout is critical to maximize the effectiveness of the LIN protection circuit.

The following guidelines are recommended:

Locate the protection devices as close as possible to the LIN connector. This allows the protection devices

to absorb the energy of the transient voltage before it can be coupled into the adjacent traces on the PCB.

Minimize the loop area for the high.speed data lines, power and ground lines to reduce the radiated emissions.

Avoid running protection conductors in parallel with unprotected conductors

Use ground planes wherever possible to reduce the parasitic capacitance and inductance of the PCB that

degrades the effectiveness of a filter device.

Using shared transient return paths to a common ground point.
