7 TVS2201 www.ti.com slvseq4 ? september 2018 product folder links: TVS2201 submit documentation feedback copyright ? 2018, texas instruments incorporated 8 detailed description 8.1 overview the TVS2201 is a bidirectional precision clamp with two integrated fets driven by a feedback loop to tightly regulate the input voltage during an overvoltage event. this feedback loop leads to a very low dynamic resistance, giving a flat clamping voltage during transient overvoltage events like a surge. 8.2 functional block diagram 8.3 feature description the TVS2201 is a precision clamp that handles 30 a of iec 61000-4-5 8/20 s surge pulse. the flat clamping feature helps keep the clamping voltage very low to keep the downstream circuits from being stressed. the flat clamping feature can also help end-equipment designers save cost by opening up the possibility to use lower- cost, lower voltage tolerant downstream ics. this device provides a bidirectional operating range, with a symmetrical v rwm of 22 v, designed for applications that have bipolar input signals or that must withstand reverse wiring conditions. the TVS2201 has minimal leakage at v rwm , designed for applications where low leakage and power dissipation is a necessity. built in iec 61000-4-2 and iec 61000-4-4 ratings make it a robust protection solution for esd and eft events and the TVS2201 wide ambient temperature range of ? 40 c to +125 c enables usage in harsh industrial environments. 8.4 device functional modes 8.4.1 protection specifications the TVS2201 is specified according to both the iec 61000-4-5 and iec 61643-321 standards. this enables usage in systems regardless of which standard is required by relevant product standards or best matches measured fault conditions. the iec 61000-4-5 standard requires protection against a pulse with a rise time of 8 s and a half-length of 20 s, while the iec 61643-321 standard requires protection against a much longer pulse with a rise time of 10 s and a half-length of 1000 s. advance information
8 TVS2201 slvseq4 ? september 2018 www.ti.com product folder links: TVS2201 submit documentation feedback copyright ? 2018, texas instruments incorporated device functional modes (continued) the positive and negative surges are imposed to the TVS2201 by a combination wave generator (cwg) with a 2- coupling resistor at different peak voltage levels. for powered-on transient tests that need power supply bias, inductances are used to decouple the transient stress and protect the power supply. the TVS2201 is post- tested by assuring that there is no shift in device breakdown or leakage at v rwm . in addition, the TVS2201 has been tested according to iec 61000-4-5 to pass a 1-kv surge test through a 42- coupling resistor and a 0.5- f capacitor. this test is a common test requirement for industrial signal i/o lines and the TVS2201 precision clamp can be used in applications that have that requirement. the TVS2201 integrates iec 61000-4-2 level 4 esd protection and 80 a of iec 61000-4-4 eft protection. these combine to ensure that the device can protect against most common transient test requirements. for more information on ti's test methods for surge, esd, and eft testing, refer to the iec 61000-4-x tests for ti ' s protection devices application report. 8.4.2 reliability testing to ensure device reliability, the TVS2201 is characterized against 5000 repetitive pulses of 25-a iec 61000-4-5 8/20- s surge pulses at 125 c. the test is performed with less than 10 seconds between each pulse at high temperature to simulate worst-case scenarios for fault regulation. after each surge pulse, the TVS2201 clamping voltage, breakdown voltage, and leakage are recorded to ensure that there is no variation or performance degradation. by ensuring robust, reliable, high temperature protection, the TVS2201 enables fault protection in applications that must withstand years of continuous operation with no performance change. 8.4.3 minimal derating unlike traditional diodes, the TVS2201 has zero derating of maximum power dissipation and ensures robust performance up to 125 c. traditional tvs diodes lose up to 50% of their current carrying capability when at high temperatures, so a surge pulse above 85 c ambient can cause failures that are not seen at room temperature. the TVS2201 prevents this so the designer can see the surge protection regardless of temperature. because of this, flat-clamp devices can provide robust protection against surge pulses that occur at high ambient temperatures, as shown in ti's tvs surge protection in high-temperature environments application report. 8.4.4 bidirectional operation the TVS2201 is a bidirectional tvs with a symmetrical operating region. this allows for operation with positive and negative voltages, rather than just positive voltages like the unidirectional tvs2200. this allows for single chip protection for applications where the signal is expected to operate below 0 v or where there is a need to withstand a large common-mode voltage. in addition, there is a system requirement to be able to withstand reverse wiring conditions, in many cases where a high voltage signal is accidentally applied to the system ground and a ground is accidentally applied to the input terminal. this causes a large reverse voltage on the tvs diode that the device must be able to withstand. the TVS2201 is designed to not break down or see failures under reverse wiring conditions, for applications that must withstand these miswiring issues. note if the applied signal is not expected to go below 0 v, a unidirectional device will clamp much lower in the reverse direction and should be used. in this case, the recommended device would be the tvs2200. 8.4.5 transient performance during large transient swings, the TVS2201 will begin clamping the input signal to protect downstream conditions. while this prevents damage during fault conditions, it can cause leakage when the intended input signal has a fast slew rate. to keep power dissipation low and remove the chance of signal distortion, ti recommendeds that the designer keep the slew rate of any input signal on the TVS2201 below 2.5 v/ s at room temperature and below 1.0 v/ s at 85 c shown in . faster slew rates will cause the device to clamp the input signal and draw current through the device for a few microseconds, increasing the rise time of the signal. this will not cause any harm to the system or to the device, however it can cause device overheating if the fast input voltage swings occur regularly. advance information
9 TVS2201 www.ti.com slvseq4 ? september 2018 product folder links: TVS2201 submit documentation feedback copyright ? 2018, texas instruments incorporated 9 application and implementation note information in the following applications sections is not part of the ti component specification, and ti does not warrant its accuracy or completeness. 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. 9.1 application information the TVS2201 can be used to protect any power, analog, or digital signal from transient fault conditions caused by the environment or other electrical components. 9.2 typical application figure 1. TVS2201 application schematic 9.2.1 design requirements a typical operation for the TVS2201 would be protecting a usb type-c v bus input, with a nominal input voltage of 20 v and a required withstand of 22 v, shown in figure 1 . in this example, a TVS2201 is protecting the input to a tps65982 type-c port controller. without any input protection, this input voltage will rise to hundreds of volts for multiple microseconds, and violate the absolute maximum input voltage and harm the device if a surge event is caused by lightning, coupling, hot-swap ringing, or any other fault condition. this customer is adding additional surge protection on the v bus line because they are worried about faulty connectors causing power spikes, and in addition wants to have protection against mechanical shorts in the connector that could possibly apply ? 20 v to the v bus line. 9.2.2 detailed design procedure if the TVS2201 is in place to protect the device, the voltage will rise to the breakdown of the diode at 26.6 v, during a surge event. the TVS2201 will then turn on to shunt the surge current to ground. with the low dynamic resistance of the TVS2201, even large amounts of surge current will have minimal impact on the clamping voltage. the dynamic resistance of the TVS2201 is around 55 m , which means a 25-a surge current will cause a voltage raise of 25 a 55 m ? = 1.37 v. because the device turns on at 26.6 v, this means the input will be exposed to a maximum of 26.6 v + 1.37 v = 27.97 v during surge pulses, robustly protecting the usb type-c port. in addition, the TVS2201 provides protection against reverse voltage application that could accidentally be caused by shorts between pins. if ? 20 v is applied to the vbus pin, the tps65982 will not be harmed because the series diode will prevent the voltage from being applied to the input, and the TVS2201 will not shunt current because the reverse working voltage is ? 22 v. if the tvs2200 or a unidirectional device is used in this case, a ? 20-v short would cause the device to shunt current until it fails. advance information
10 TVS2201 slvseq4 ? september 2018 www.ti.com product folder links: TVS2201 submit documentation feedback copyright ? 2018, texas instruments incorporated typical application (continued) finally, the small size of the device also improves fault protection by lowering the effect of fault current coupling onto neighboring traces. the small form factor of the TVS2201 allows the device to be placed extremely close to the input connector, which lowers the length of the path fault current going through the system compared to larger protection solutions. 10 power supply recommendations the TVS2201 is a clamping device so there is no need to power it. to ensure the device functions properly do not violate the recommended v in voltage range ( ? 22 v to 22 v) . advance information
11 TVS2201 www.ti.com slvseq4 ? september 2018 product folder links: TVS2201 submit documentation feedback copyright ? 2018, texas instruments incorporated 11 layout 11.1 layout guidelines the optimum placement is close to the connector. emi during an esd event can couple from the tested trace to other nearby unprotected traces, which could result in system failures. the pcb designer must minimize the possibility of emi coupling by keeping all unprotected traces away from protected traces between the tvs and the connector. route the protected traces straight. use rounded corners with the largest radii possible to eliminate any sharp corners on the protected traces between the TVS2201 and the connector. electric fields tend to build up on corners, which could increase emi coupling. ensure that the thermal pad on the layout is floating rather than grounded. grounding the thermal pad will impede the operating range of the TVS2201, and can cause failures when the applied voltage is negative. a floating thermal pad allows the maximum operating range without sacrificing any transient performance. 11.2 layout example figure 2.
