5.3 Electrostatic Property
There is no overvoltage protection inside the C16QS module.
The ESD protection is required when the module is used to ensure product quality.
ESD design recommendations:
✓ The USB port needs to add TVS on VDD, D+, D- for protection, and the TVS parasitic capacitance on
D+/D- is <2pF
✓ The module's USIM card external pin needs to be protected by TVS, and the parasitic capacitance
requirement is <10pF
