USB Type-C interface electrostatic protection scheme

sohu | SOCAY Elec | 06/05/2021

The naming primitive for the USB Type-C interface is the USB Type-C connector, which is a robust and easy-to-use interface. Support positive and negative insertion, convenient and fast. Supports ultra-high rate communication function and power output. The maximum transmission rate is 10Gbits/S, the maximum output power is 100W, and the maximum current is 5A. The size is 8.3mm X 2.5mm.

It has 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): DP , MHL, Audio signals are all reconfigured and share interfaces.

One. Application background

The working characteristics of the Type-C interface means that it needs to support hot-swappable actions, so it is more susceptible to human body electrostatic discharge damage. Its internal is a highly integrated chip, and the damage of electrostatic discharge will make the interface more fragile. At the same time, the Type-C interface has a higher data transmission rate and has stricter requirements on the data transmission error tolerance rate. In response to this kind of electrostatic protection requirements and the actual circuit environment SOCAY has designed a USB Type-C interface electrostatic protection program. The following introduces the specific content of the program:

Two. Protection scheme and SOCAY device

Transient suppression diode (TVS)

TVS【SMF24A】Vbr: 26.7-29.5V; Ir: 5μA; Vrwm: 24.0V, Ipp: 5.14A; Vc (V): 38.9V; Package: SOD-123FL

Electrostatic diode (ESD)

ESD【ESD05V88D-LC】Vrwm: 5.0V; Vb: 6.0V; anti-static capability (contact/air): 8KV/15KV; junction capacitance (f=1MHz): 0.3pF; package is SOD-882

Four. Program description and precautions

1. In the power supply part of the Type-c interface, a large current TVS is used for surge and electrostatic protection against the ground

2. Array ESD is used in the signal part, which is small in size, saves PCB space and is easy to design

3. Use low capacitance ESD devices to meet high-speed transmission requirements
