Hi,
1. in datasheet pin 10,9,15 are GND2.
But we measured that pin 10 are not shorted with PIN9 and PIN15. Around 20Mohm measured with multimeter.
2. My customer now has several bad devices, the bad devices are found when the CAN communication cannot be accomplished on board. The board schematic is as shown below.
We unsoldered the bad devices, finding that CANH and CANL are shorted to GND2 with <1kohm measured with multimeter. The resistance measured on good devices are around 850kohm.
Are there any risk of the schematic below?
