Other Parts Discussed in Thread: STRIKE
Hi team,
My customer did an ESD test for TLIN1028-Q1 LIN cable. Their LIN trace does not have TVS.
When they force a ESD strike to LIN cable, their MCU was reset by RST output of this device.
Since they cannot change their PCB due to the project schedule, and their RST trace has a dummy pad for capacitor, they put 0.1uF capacitor at RST trace and it improved the MCU reset phenomenon. It may keep 5V by capacitor even though RST output Low momently.
Could you give me your advice whether is it okay that they put 0.1uF capacitor at RST trace?
If the stress is too high, they can accept to reduce the capacitance to 4700pF.
Best Regards,
