We have used CAN SN65HVD230 in our BMS board. Testing is done in Lab, using a CAN to USB convertor and a PC. Worked fine.
Product is in pilot production now. We are seeing lot of failures of CAN IC.
Please review my schematic and suggest any improvement to be done .
Pin5= floating // Pin8= shorted to Gnd
R219=R220=330k // R262=100E (changed to 120 ohm later. Seeing failures with 120 ohm too)
D73= NOT USED
