I have this protection circuit on the USB power to my circuit. It has a ferrite bead (L2) and a set of TVS diodes (D3), but it's still susceptible to static electricity resetting the circuit.
The static hits the ground shield on the USB connector - should that shield be left floating? Have it's own protection circuit to discharge static to ground? Or should the ferrite bead and TVS diodes be able to handle more current?
Thanks very much!
