Please find below schematic. We are seeing CAN IC failure on field with no filter capacitor (C6, C7, C8). Please suggest how to size them for better reliability. We are operating at 500kbps, and data send frequency of 500ms. There are 4 nodes in the CAN network. Our node is a stub node with below specs. 2 other nodes have 120 ohm each, 1 other stub node has 1kohm termination resistor.
Typical failure cases are: VCC-GND Short. Few other cases, we are working, will update soon. C24 is 10mm far from IC.
