PCB of the day! HUSB238 USB PD Sink Breakout 🔌🔋💡

USB C has a nifty power management system where, by default, you can get a classic 5V at 1A power out from a power supply or port, but with some fancy twiddling, you can request higher voltages and currents. We've always wanted a simple breakout that could get you a range of voltages using just jumper pads, but we only had a little luck with IP2721. Then we found this chip - the HUSB238 https://en.hynetek.com/pdsink.html - used in a USB-to-DC cable, which seems perfect! It can do 5V to 20V with just a resistor setting and set the current. There's also an I2C interface that can be used to set them if the settings are persistent - we'll have to try it out. There's a library here if you want to see what the registers are like https://github.com/ltyridium/HUSB238-lib. Here's our draft for a breakout design.

[圖]快充混戰局面即將緩解：谷歌要求新安卓設備必須兼容USB-PD

就像以往的新標準一樣，部分設備製造商喜歡使用自己的快充方式。根據外媒Android Authority此前進行的測試：一加的Warp Charge、三星的Fast Charge以及其他廠商的專有快充技術，對第三方配件的兼容性都不是很好。因此為了能夠獲得最佳的快充體驗，用戶必須要使用包裝盒中隨附的適配器。

XDA Developers指出在Android 7 Nougat中，谷歌只是建議開發商避免專有的快充方式，並表示在未來將會“要求所有的Type-C設備支持標準的Type-C適配器”。而現在谷歌已經開始規範，並強制要求提高兼容性。

在這份技術文檔中，另一項值得關注的變化就是對Digital Wellbeing的硬性要求。該功能隨Android 9 Pie系統引入，可以監控應用程序的使用和通知，調整屏幕的顏色配置文件以減輕眼睛疲勞等，以及其FamilyLink家長控制功能（可幫助家長進行監控）並控制他們家人的設備。

根據該文件，製造商使用Android 9或Android 10的新手機和平板電腦中需要逐步實現這些功能，並且2019年9月3日之後設備更新中也必須包含這些功能。該文件據稱表明Google將接受製造商提供的定制解決方案，只要它們提供與Digital Wellbeing和Family Link相同的功能集即可。

Does the TYPE-C connector support fast charging?

Nowadays, the Type-C connector is not only the charging interface for many cell phones, but the Type-C connector is also widely used in computers and flash drives. Why do people like Type-C connectors so much?

People's shared understanding of Type-C connectors is no need to distinguish between positive and negative and faster-charging speed.

This article will analyze in detail TYPE-C connector is not fast charging. Let's take a look at it below.

TYPE-C connector, also known as USB-C, is the interface standard for electronic devices. Today, the Type-C connector standard is integral to fast charging technology.

With the development of network technology, cell phones are increasingly dependent on the network Type-C connector standard. When the network speed is faster, the more problems the phone has to deal with at the same time, the more power consumption.

To reduce the power consumption of cell phones, we can start from two aspects: cell phone battery update and charging technology.

However, there is no breakthrough in cell phone battery technology.  To change the immediate power consumption of cell phones, the development of fast charging technology is significant.

Currently, two kinds of fast charging technologies are commonly used: boosting the power adapter's output voltage (appliance-powered power conversion device, usually called the charger head) by outputting a high current to increase the charging power.

By comparison, it is found that higher efficiency can be obtained when charging at low voltage and high current under the same power conditions.

The fast charging head needs to convert the AC power in daily life to the specified voltage and current to ensure charging safety. Also, it must use memorable fast charging lines and interfaces for voltage current transfer.

The Type-C connector has several times more contact points than a traditional interface, making it more current and better suited for fast charging technology.

Current USB power transfer protocols are not uniform and can be compatible with charging voltages of 5 V/12 V/20 V and charging currents of 1.5 A/2 A/3 A/5 A/5 A.

The increase in charging volume requires correspondingly higher security of the interface chip. The Type-C connector and USBPD can achieve 100 W of charging power at high voltage and high current output.

Therefore, the cell phone charging fast can meet the Type-C connector standard and is an integral part of the fast charging technology.

PCB of the day! Requiem for a 5.1K CC resistor 🔌💡🔧

We have a few gadgets around the house that, despite having a USB type C connector, do not abide by the USB C power delivery specification! They leave off or mis-connect the two 5.1K resistors required to tell a USB PD wall adapter that they want 5V 1A power, a common issue because the devices work fine with a USB A to C cable, and only Macbooks seem picky about this stuff: cheap power supplies blast 5V and call it a day. This doo-hickey is a solution. It has two USB sockets nestled back-to-back, and instead of connecting the CC lines through, each half has its own dedicated resistor set. It makes for an excellent symmetrical design. Pair it with a short USB C-C cable to create an inline extender. We considered having one side be a plug, but the SMT-able plug connectors seemed like they needed to be more mechanically stable.

The most comprehensive interpretation of the USB Type-C connector standard

USB Type-C (USB-C) is the latest USB interface standard, and its application in various fields is rapidly spreading. This article describes the performance characteristics of the USB-C connector, as well as the USB-C related USB PD and USB 3.1 second generation and other related power and data transmission specifications and features, while using CUI's USB-C interface products for For example, the selection of USB interface products is introduced to help developers understand the USB-C standard and select the high-quality USB-C interface or cable assembly.

"Faster, higher, stronger" is our familiar Olympic motto. If you use this adage in the electronics industry, it should be "faster, smaller, easier to use" - this is the new standard for USB connectivity. Shouting.

As you may have already seen, the latest USB Type-C (USB-CTM) ports are widely used in the next generation of computing products currently on sale, and this trend is expected to be further strengthened in the future, as USB-C is available through a single cable. A unique ability to connect to transmit data, power, and even audio.

Market analyst firm ABIResearch believes that we have reached the critical point of USB Type-C commercial; by 2021, global shipments of smartphones equipped with such USB connectors are estimated to reach 830 million units.

With a width of only 9mm and a height of only 3.5mm, this connector is much smaller than previous generations of connectors, allowing device manufacturers to develop smaller devices. Its advent is just the right time to perfectly meet the needs of emerging products, such as home automation and IoT devices, including smart sensors that work seamlessly with this smaller, simpler, latest connector package.

Unusable ease of use

Cables for USB-C applications can be plugged in from either end to meet the power requirements of devices such as laptops, eliminating the need for users to carry multiple cables for different purposes.

This versatility stems from a more complex structure inside the connector (Figure 1). First, it has more wires. USB Type-A and Type-B connectors require four or five wires - unlike them, USB-C includes 24 contacts, allowing bidirectional insertion, and supports four power and ground pairs, as well as two signal pairs. . In addition, its rated durability has increased to 10,000 insertions and exports, a significant increase from the previous version of 1,500 plugs.

The USB-C's power and ground pair are rated for voltages up to 20V, current ratings are increased, and the total rating is 5A, providing up to 100W of power transfer over a single USB-C connection. In addition, each data pin pair can manage data transfer rates of up to 10 Gbps, which means the connector's total transfer capacity reaches 20 Gbps.

Faster data and higher power transfer

The latest data and power specifications of USB-IF force us to significantly increase the USB-C's transmission capabilities, especially in USB Power Delivery (USB PD), USB 3.1 Generation 2 and recently finalized USB 3.2 high-speed data specifications:

USB PD utilizes all four power and ground pairs to maximize the USB-C's 100W power transfer capability

USB 3.1 Generation 2 uses a set of data channels to define a 10Gbps transfer rate

Similarly, USB 3.2 controls two sets of 10 Gbps data channels to maintain transmission rates of up to 20 Gbps.

Conceptually, distinguishing the USB-C standard (physical connections only) from USB PD and high-speed data specifications (including USB 3.1 Generation 1 (SuperSpeed) and USB 3.1 Generation 2 (SuperSpeed +), and USB 3.2) Opening is very important.

For example, although the USB-C connector is designed to support the USB PD standard, to negotiate and manage power delivery to interconnected devices, a USBPD-compatible host controller must still be available. In addition, the cable must be configured to support this standard.

USB PD not only increases power, it also facilitates bidirectional power transfer, which greatly increases the flexibility of charging and powering user equipment. On this basis, since the USBPD can perform power negotiation through the VBUS connection instead of using a data connection, it can simultaneously transmit power and data streams.

Table 1 shows the upgrade process of USB transport capabilities in recent generations.

In terms of high-speed data specifications, the second generation of USB 3.1 defines data and power signals, but does not specify physical connections. This allows us to connect USB 3.1 Gen 2 devices with conventional Type-A or Type-B connectors and cables and achieve data transfer rates of 10 Gbps as long as they have sufficient current, voltage and signal integrity characteristics. Similarly, we can use a simple hardware adapter to provide traditional connectivity standards such as USB 2.0 using a USB-C connector.

High quality USB-C connector selection

Obviously, not all USB-C connectors or cable assemblies are “born equal”, and premium products offer better performance and more reliable communication over longer cables.

In addition to considering the quality of materials and USB-C connectors for future products, designers can choose between two versions of Type-C sockets, see Figure 2. Traditionally, standard SMT mounting sockets are located above the PCB. In this case, however, the total assembly height is the sum of the PCB thickness and the connector height. Alternatively, the intermediate mount connector can be mounted to the recess in the PCB; although this reduces the overall assembly height, the intermediate mount connector does not allow for signal lines to be routed under the connector.

Summary of this article

In the consumer electronics market, the use of USB Type-C connectors is rapidly gaining popularity. To meet this ever-increasing demand, electronic component manufacturer Konnra Electronics offers a range of high quality USB Type-C plugs and sockets, including SMT and intermediate mounting types. These connectors are designed to achieve the communication rates defined in the USB 3.1 Gen 2 specification while meeting the current and future needs of designers.
