The TPD4E004 is rated to dissipate contact ESD strikes of ±8-kV contact and ±12-kV air-gap, meeting Level 4 as specified in the IEC 61000-4-2 international standard. This device has a 1.6-pF IO capacitance per channel, making it ideal for use in high-speed data IO interfaces. 7.2 Functional Block Diagram VCC IO1 IO3 IO2 IO4 GND 7.3 Feature Description TPD4E004 is a TVS which provides ESD protection for up to four channels, withstanding up to ±8-kV contact and ±12-kV air-gap ESD per IEC 61000-4-2. The monolithic technology yields exceptionally small variations in capacitance between any IO pin of TPD4E004. The small footprint is ideal for applications where space-saving designs are important. 7.4 Device Functional Modes The TPD4E004 device is a passive integrated circuit that triggers when voltages are above VBR or below the diodes VF of approximately –0.3 V. During ESD events, voltages as high as ±8-kV contact and ±12-kV air-gap ESD can be directed to ground via the internal diodes. Once the voltages on the protected line fall below the trigger levels of TPD4E004 (usually within 10’s of nano-seconds) the device reverts back to its high-impedance state.

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 TPD4E004 is a diode array type TVS which is typically used to provide a path to ground for dissipating ESD events on hi-speed signal lines between a human interface connector and a system. As the current from ESD passes through the TVS, only a small voltage drop is present across the diode. This is the voltage presented to the protected IC. The low RDYN of the triggered TVS holds this voltage, VCLAMP, to a tolerable level for the protected IC. 8.2 Typical Application VBUS 0.1 µF VCC D+ D– RT GND IO4 IO1 USB Controller IO3 IO2 VBUS D+ GND D– GND Figure 5. Application Schematic 8.2.1 Design Requirements For this design example, a single TPD4E004 is used to protect all the pins of two USB2.0 connectors. Table 1 lists the design parameters for the USB application. Table 1. Design Parameters DESIGN PARAMETER VALUE Signal range on IO1, IO2, IO3, and IO4 0 V to 3.6 V Signal voltage range on VCC 0 V to 5.5 V Operating Frequency 240 MHz 8.2.2 Detailed Design Procedure When placed near the USB connectors, the TPD4E004 ESD solution offers little or no signal distortion during normal operation due to low IO capacitance and ultra-low leakage current specifications. The TPD4E004 ensures that the core circuitry is protected and the system is functioning properly in the event of an ESD strike. For proper operation, see the the following layout and design guidelines should be followed: 1. Place the TPD4E004 solution close to the connectors. This allows the TPD4E004 to take away the energy 8 Submit Documentation Feedback Copyright © 2008–2016, Texas Instruments Incorporated Product Folder Links: TPD4E004 TPD4E004 www.ti.com 2. 3. 4. 5. SLVS729B – FEBRUARY 2008 – REVISED MARCH 2016 2016 associated with ESD strike before it reaches the internal circuitry of the system board. Place a 0.1-μF capacitor very close to the VCC pin. This limits any momentary voltage surge at the IO pin during the ESD strike event. Ensure that there is enough metallization for the VCC and GND loop. During normal operation, the TPD4E004 consumes nA leakage current. But during the ESD event, VCC and GND may see 15-A to 30-A of current, depending on the ESD level. Sufficient current path enables safe discharge of all the energy associated with the ESD strike. Leave the unused IO pins floating. In this example of protecting two USB ports, none of the IO pins will be left unused. The VCC pin can be connected in two different ways: (a) If the VCC pin is connected to the system power supply, the TPD4E004 works as a transient suppressor for any signal swing above VCC + VF. A 0.1-μF capacitor on the device VCC pin is recommended for ESD bypass. (b) If the VCC pin is not connected to the system power supply, the TPD4E004 can tolerate higher signal swing in the range up to 5.8 V. Please note that a 0.1-μF capacitor is still recommended at the VCC pin for ESD bypass. 8.2.3 Application Curves Figure 6 is a capture of the voltage clamping waveform of TPD4E004 during an +8kV Contact IEC 61000-4-2 ESD strike. 120 100 Amplitude (V) 80 60 40 20 0 –20 0 5 10 15 20 25 30 35 40 45 50 Time (ns) Figure 6.

Route the protected traces as straight as possible. Eliminate any sharp corners on the protected traces between the TVS and the connector by using rounded corners with the largest radii possible. – Electric fields tend to build up on corners, increasing EMI coupling. 10.2 Layout Example D1 TPD4E004 1 D1 D2 D2 Legend VIA to Internal GND Plane VIA to Internal VBUS Plane Pin to GND Signal VIA in SMD Pad Layer 1 Routing Layer 2 Routing Figure 7.

Unless TI has explicitly designated an individual product as meeting the requirements of a particular industry standard (e.g., ISO/TS 16949 and ISO 26262), TI is not responsible for any failure to meet such industry standard requirements. Where TI specifically promotes products as facilitating functional safety or as compliant with industry functional safety standards, such products are intended to help enable customers to design and create their own applications that meet applicable functional safety standards and requirements. Using products in an application does not by itself establish any safety features in the application. Designers must ensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products in life-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use. Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., life support, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, all medical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S. TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product). Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applications and that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatory requirements in connection with such selection. Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s noncompliance with the terms and provisions of this Notice.
