TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information When a system contains a human interface connector, it becomes vulnerable to large system-level ESD strikes that standard ICs cannot survive. Protection products are typically used to suppress ESD at these connectors. TPD2S017 is a two-channel ESD protection device. In each channel, it contains two-stage TVS diodes and a resistor between the two clamping stages as an isolation. This implementation provides good clamping performance, minimal signal distortion and the support of high data speed. 8.2 Typical Application Figure 6. Typical Application Schematic 8.2.1 Design Requirements For this design example, a TPD2S017 will be used to protect the USB 2.0 high-speed data lines. The following system parameters are known. Table 1. Design Parameters DESIGN PARAMETER VALUE High-speed mode high-level output voltage 400 mV ±10% High-speed mode low-level output voltage 0 V ± 10 mV USB 2.0 high-speed data rate 480 Mbps Required IEC 61000-4-2 ESD Protection ±8-kV Contact Copyright © 2009–2015, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Links: TPD2S017 |
