The naming primitive of USB type-C interface is USB type-C connector, which is a reliable and easy-to-use interface. Support positive and negative insertion, convenient and fast. It supports ultra-high speed communication and power output function, with transmission rate extremum of 10Gbits / s, output power extremum of 100W and current extremum of 5A. Size 8.3mm x 2.5mm. Good technical compatibility: (1) vertical compatibility (compatibility with old equipment): simple compatibility with USB2.0, low-cost conversion; (2) Horizontal compatibility (compatibility with other protocols): all DP, MHL and audio signals can be reconfigured to share the interface.

3、 Scheme Application

1. Mobile phone

2. Laptop

3. Flat plate

4. Other equipment with type-C port

4、 Scheme description and precautions

1. In the power supply part of type-C interface, a large current TVs is used for surge and electrostatic protection to the ground

2. The signal part uses array ESD, which is small in size, saves PCB space and is convenient for design

3. Low Capacitance ESD devices are adopted to meet the requirements of high-speed transmission
