Application information The PESD1LIN is designed for the protection of one LIN bus signal line from the damage caused by ESD and surge pulses. The PESD1LIN provides a surge capability of up to 160 W per line for a 8/20 s waveform. power application (e.g. electro motor, inductive loads) application (e.g. voltage regulator and microcontroller) CBAT BAT LIN LIN transceiver 24 V LIN node connector CMASTER/SLAVE 15 V GND PESD1LIN 006aaa678 Fig 6. Typical application: ESD protection of one automotive LIN bus line Circuit board layout and protection device placement Circuit board layout is critical for the suppression of ESD, Electrical Fast Transient (EFT) and surge transients. The following guidelines are recommended: 1. Place the PESD1LIN as close to the input terminal or connector as possible. 2. The path length between the PESD1LIN and the protected line should be minimized. 3. Keep parallel signal paths to a minimum. 4. Avoid running protection conductors in parallel with unprotected conductor. 5. Minimize all Printed-Circuit Board (PCB) conductive loops including power and ground loops. 6. Minimize the length of the transient return path to ground. 7. Avoid using shared transient return paths to a common ground point. 8. Ground planes should be used whenever possible. For multilayer PCBs, use ground vias. PESD1LIN_2 Product data sheet (c) NXP B.V. 2008. All rights reserved.
