Visualizing: USB-C Safety: OVP, OCP, and OTP Explained
A high-wattage charger is a powerful electrical device. Safety circuits are what prevent fire.
Core Protections
- OVP (Over Voltage): Shuts down if voltage spikes.
- OCP (Over Current): Prevents drawing too much power.
- OTP (Over Temperature): Throttles power if the GaN chips get too hot.
Always check for the UL or CE mark on the brick itself.
Technical References
- IEC 62368-1: Audio/video, information and communication technology equipment.
