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.

    New Protocol Authenticates USB Type-C Chargers, Devices

    The USB Implementers Forum (USB-IF) on Wednesday announced the launch of the USB Type-C Authentication Program, which aims to protect host systems against non-compliant chargers and potentially malicious devices.

    The USB Type-C Authentication specification, unveiled by the USB-IF and the USB 3.0 Promoter Group in 2016, provides the cryptographic mechanisms needed for authenticating various types of USB Type-C devices, including chargers, cables, storage drives and power sources.

    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.

    Why USB3 Type-C Isn’t on More Cases | How Cables Are Made Factory Tour

    This factory tour shows how cables are made, especially USB 3.1 Type-C cables, in SanDian’s factory in China. Cooler Master uses this factory for its cables.

    Part of this factory’s testing is to establish that its USB 3 and Type-C cables actually reach rated speeds (some factories make fake USB 3 cables that don’t reach speeds advertised), but it also looks at how long USB cables actually last by doing endurance connection cycle testing.

    Add USB-C To Your Laptop (Almost)

    [BogdanTheGeek] has done, in adding a USB-C port to his Acer.

    Of course, the port in question isn’t a fully functioning USB-C one, it’s a power supply jack, and it replaces the extremely unreliable barrel jack the machine was shipped with.

    Add USB-C PD to your $#!7 laptop

    The aim of this project was to replace my horrible barrel jack charging port on my Acer Spin 1 with a type-c port

    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.

    A USB-C Bench Power Supply

    A bench power supply is one of those things that every hacker needs, and as the name implies, it’s intended to occupy a place of honor on your workbench. But with the addition of USB-C support to his DPH5005 bench supply, [Dennis Schneider] is ready to take his on the road should the need ever arise.

    Ruideng DPH-5005 with USB-C

    My model, DPH5005, offers 50V/5V on input and output and is a combined buck/boost regulator. Sounds good, doesn’t it? I ordered it with a case and just had to find a way to equip it with USB-C and USB-PD to source it from my 45 Watts power bank.
