New USB Type-C Connector

USB Type-C Connector is on the news today as they have introduced another new type of USB connector that is not directly compatible with any existing connectors. USB Type-C Connector Specifications Finalized article tells that today the USB-IF (USB Implementers Forum) announced that the latest USB connector which we first caught a glimpse of in April has been finalized. This Type-C specification tries to correct many of the issues with previous USB as a connector models. There are a lot of changes coming, with some excellent enhancements. Check USB Type-C Connector Specifications Finalized and Reversible USB Type-C connector finalized: Devices, cables, and adapters coming soon articles for details. The new connector is for example has reversible plug orientation, similar size to micro-USB, ertified for USB 3.1 data rates (10 Gbps) and support higher power charging.

With this new design, existing devices won’t be able to mate using the new cables, so there are specifications for adapter cables. There will be some time until this new connector becomes widely used. One issue on mobile devices might be the the fact that China, the EU, and the GSMA have all agreed that new mobile devices use Micro-USB for charging  (solution could maybe be including a Micro-USB-to-Type-C adapter with every new smartphone).

    Everything Wrong With USB-C Cables

    USB-C has caused a lot of confusion. As Apple and other companies push to include only USB-C ports consumers are left with a lot of headaches. Two USB-C cables that look the same can transfer data and power at different speeds. And not all USB-C to headphone jack adapters are compatible. It’s time to clear up the confusion and find the right cable for your device.


    video is more confusing than the technology itself

    This is the same for other USB mobile/tablet charging cables.
    USB type c is better than micro USB cable

    Conclusion: Don’t use cheap cables.

    Stop saying this is a problem with USB C. This is a problem with USB itself and the lack of standardization around manufacturers and the lack of proper product labeling. Type C is simply the shape of the plug and has nothing to do with any of the problems you mentioned. These were problems with USB Type A, Mini USB, Micro USB and all the other USB connector interfaces as well.

    Designing with Waterproof USB Type-C Connectors
    Waterproof USB Type-C connectors are emerging as the go-to solution for today’s consumer products.

    While legacy USB and Micro USB connectors have been the standard for connectivity, USB Type-C is becoming the preferred connector solution for consumer products because it offers higher performance, combined power and data connectivity, and a form factor that fits today’s products. True IPX8-rated waterproof versions of USB Type-C connectors are increasingly needed to meet customer requirements.

    The iPhone, Samsung Galaxy, Huawei’s high-end phones, and other mobile phones tout their water resistance as one of the attributes that consumers want. This attribute also applies to other products like electric shavers, electric toothbrushes, POS terminals, and wearables, as well as automotive, medical, and industrial products. The last thing users need to worry about is environmental sensitivity in an electrical product.

    Another trend is faster operation—users want products to transfer data and charge up more quickly. The market is transitioning from Micro USB to USB Type-C because USB Type-C delivers far higher power and data rates. For example, a product with Micro USB might have used 0.9 A (with USB 3.0), but with USB Type-C it can use 5 A, so it can charge much faster. And while Micro USB data-transfer rates were in the 5-Gb range, USB Type-C data transfers can deliver up to 10 Gb/s.

    USB Type-C connectors are easier to use than Micro USB because they offer flip insertion (no specific connector orientation is required when inserting them).

    USB Type-C connectors with IPX8 waterproofing performance are becoming the new standard for a wide range of products because they deliver go-anywhere reliability, faster charging, and faster data transfers.

    USB Type-C Controller Targets Fast Charging of Portables in Vehicles

    This automotive-qualified part simplifies the design of in-vehicle charging ports by minimizing the need for external components.

    Cypress Semiconductor’s EZ-PD CCG3PA is a USB Type-C and Power Delivery (PD) controller targeting fast charging of portable electronics in vehicles. The controller is designed to deliver a plug-and-play user experience to automotive charging ports by providing support for the USB PD 3.0 standard with a programmable power supply (PPS), Qualcomm’s Quick Charge (QC) 4.0+ protocol, and legacy charging standards.

    By way of review, the USB PD standard enables the power delivery of USB power up to 100 W, sufficient to drive large devices such as laptops.

    Qualcomm’s Quick Charge 4+ chargers enable devices to be charged without Quick Charge technology or the Snapdragon architecture inside them. This is possible because Quick Charge 4+ supports USB PD as its primary communication protocol.

    As standards continue to evolve, compliance and interoperability pose an ongoing challenge, but the EZ-PD CCG3PA overcomes these issues with firmware upgradeability.

    The big problem with fast charging using USB Type-C cables

    Cable-to-device connections can accumulate contaminants, causing them to heat up quickly, which can easily damage or destroy the cable and the mobile device. The fix: better circuit design with temperature monitoring.

    Fast chargers and cables compliant with USB-PD and USB Type-C specifications can support charging power levels up to 100 W.

    From a safety standpoint, USB‑C cables must be capable of carrying appropriate voltages and currents.

    The sources of USB‑C charging damage
    The pin pitch of USB‑C connectors is 0.5 mm ― much tighter than the 2.5-mm pin pitch in USB Type-A connectors. This tighter pitch significantly increases the risk of a fault that could cause a thermal event.

    resistive faults can cause a dangerous temperature rise while increasing current only minimally. Damage to both cables and devices, even fire, has been reported

    : a setP digital temperature indicator is placed on the connector’s CC line, and when it senses temperatures higher than 100°C, it switches from a low-resistance state to a high-resistance state.

    The charging system assumes that the cable has become detached because the voltage is higher than the value set forth in the specification, so the charging system turns off the power through the VBUS line.

    This prevents the connector, cable, and device being charged from overheating.

    … Apple software engineer Forrest Heller broke down the specs for three consumer USB-C chargers, including the Google Pixel 18-Watt Charger, Huawei 40-Watt SuperCharge, and the Anker PowerPort Atom PD 2.
    Heller compares the Random Access Memory (RAM) between an 18-watt Google Pixel USB-C charger and the Apollo Guidance Computer, for instance. He found that the Anker charger has eight kilobytes of RAM compared to the Apollo computer, meanwhile, has four kilobytes of RAM.
    After looking at RAM, clock speed, program storage space, and a few other components, Heller concluded that today’s USB-C chargers are more or less 563 times faster than the Apollo computer.

    USB-C-liitäntä sovellukseen helposti

    USB-liitännällä on aina ollut kyky tarjota laitteille syöttötehoa, kunhan 5 voltin jännite ja alle 1,5 ampeerin virta riittävät käyttökohteen tarpeisiin. Tämä on rajoittanut liitännän aiemmat A- ja B-versiot vain pienten elektroniikkalaitteiden tehonsyöttöön: USB-muistit, näppäimistöt, ladattavat pienlaitteet, matkapuhelimet. USB-C toi sitten mukanaan uuden PD-standardin (Power Delivery), joka antaa syöttävälle laitteelle mahdollisuuden siirtää liitettyihin laitteisiin jopa 100 watin tehoja 5 – 20 voltin jännitteellä.

    Alun perin USB-C- ja Power Delivery -toteutukset olivat hyvin monimutkaisia sisältäen paljon ulkoisia komponentteja ja vaatien ohjelmistojen konfigurointivälineitä. Nykyään puolijohdeteollisuudessa on kehitetty uusia piirejä, jotka poistavat kaiken epävarmuuden USB-C-liitännän suunnittelusta. Mitä nykyään sitten vaaditaan, jos suunnittelija haluaa lisätä USB-C-liitännän omaan tuotteeseensa?

    USB-C-toteutuksista yksinkertaisimpia on pelkkä latausliitäntä. Tässä tapauksessa järjestelmä on suunniteltu vain syöttämään ja/tai lataamaan tehoa siihen kytkettyyn laitteeseen. Esimerkkejä tämän tyyppisestä järjestelmästä ovat auton takapenkin latausliitäntä, sähkötyökalun akkulaturi tai kotikäyttöön tarkoitettu seinälaturi.

    Tässä tapauksessa järjestelmän toteuttamiseen vaadittavien komponenttien BOM-lista (Bill of Materials) on suhteellisen lyhyt:

    USB-C-porttiohjain: Ohjaa kytkentää ja jaettavaa tehoa.
    DC/DC-muunnin: Muuttaa tulojännitteen PD:n määrittämäksi Vbus-väyläjännitteeksi.
    Kuormakytkin: Syöttää 5 voltin jännitteen pistokkeen Vbus-väylään ja yhdistää oikean Vbus-jännitteen heti, kun PD on määrittänyt sen. On joskus yhdistetty DC/DC-muuntimeen.
    LDO: reguloi porttiohjaimelle menevän jännitteen, koska DC/DC-muunninta voidaan tarvita 5 – 20 V jännitteen syöttämiseen.

    Niin kauan kuin ohjain on PD 3.0 -yhteensopiva, käyttäjällä on pääsy kaikkiin tehonjakelun standardiprofiileihin: 15W/27W/45W/60W/100W.

    DC/DC-muuntimen tyypin valinta riippuu lähinnä tulojännitteestä. Teholähteen on aina kyettävä antamaan lähtöjännitteeksi 5 – 20 VDC, jotta se olisi täysin PD-yhteensopiva. Järjestelmille, joissa tulojännite on 24 VDC, tai yleensäkin yli 20 VDC, alaspäin muuntava buck-topologia voi tarjota kustannustehokkaan ratkaisun. Alemmilla tasajännitteillä toimiville tai offline-tilassa toimiville AC-järjestelmille vaaditaan muita topologioita.

    Even though it’s been around for a few years, there’s still a lot of confusion surrounding USB-C.

    USB-C was supposed to be a universal connector — but it still has a lot of problems

    USB-C has caused a lot of confusion for phone and laptop users alike — two cables that look the same can transfer data and power at different speeds.
    Not all USB-C to headphone jack adapters are compatible and good USB-C headphones are still tough to find.

    Even though it’s been around for a few years, there’s still a lot of confusion surrounding USB-C. It was supposed to be a universal connector, bridging together phones, computers, power supplies, and accessories. But there’s one big issue holding it back. The USB-C name refers to the physical shape of the connector, not the protocol. Even though two cables can have the same physical connector, what’s happening on the inside can be very different. The protocol, or specification, determines what the cable can transfer and how fast it can send it. A USB-C cable can be limited to either USB 3.1, 3.0, or 2.0 speeds. Some USB-C cables are USB 3.1 Gen 2 cables.

    To make things more confusing, some USB-C cables can be used with a second monitor, while others aren’t capable of sending a video signal at all. You could easily end up stranded if you mix up two different cables. And things can get even more complicated when you’re using adapters to change from USB-C to another connector

    Okay, so your data might transfer slower, or you might mix up two different cables, but what’s the harm? Well, USB-C cables are also responsible for transferring power. The stakes are much higher when you’re relying on a cable to send the correct amount of electricity to your device. Many smartphones and laptops can charge over USB-C, but the amount of power that these cables can deliver isn’t necessarily the same. In some cases, a laptop can require almost twice as much power as a smartphone. The consequences of using the wrong cable can be worse than a slower charge. If

    USB-C Makes Compelling Case as EU Moves Toward Single Charging Standard

    The European Parliament recently voted to recommend a single, universal charger for all mobile phones and portable devices sold in Europe. USB-C could become that single-cable standard.

    In January, members of the European Parliament voted to recommend a single, universal charger for all mobile phones and portable devices sold in Europe. By a 550 to 12 vote, they argued that standardization on a single charger would not only reduce e-waste, but also be more cost-effective for consumers. What’s more, a group that champions environmental interests across the EU, named the European Environmental Citizens’ Organization for Standardization, is recommending that USB-C become that single-cable standard.

    USB-C is the “Holy Grail” of wired connectivity. It offers bidirectional data and power, and a tiny, orientation-agnostic connector that’s the same on both ends of the cord. And, because it carries up to 100 W of power, USB-C can truly become the one connector for any type of electronic device with a power adapter.
