Power of USB Power Delivery

February 21, 2019 at 8:00 AM

 

In this blog, we’ve talked a lot about USB. From USB 3.1 to USB 3.2, and even vibration-proof USB, USB is always reinventing itself, so it’s no wonder that it remains a powerfully popular interface. Now, USB is taking another step in its progression with USB power delivery, a fast charging technology with significantly higher power levels than standard charging. Here, we’ll take a look at the power of USB power delivery.

 

In the beginning, USB was merely a data interface that was able to provide a limited supply of power. Today, USB has evolved into a main power provider with a data interface. Thus, many things now use USB ports including cars, aircraft, laptops and wall sockets to charge or power devices and transfer data easily. In order to build on these existing USB functions, USB power delivery (USB-PD) has been developed to allow for maximum functionality of USB by delivering data and increased flexible power over a single cable.

 

USB-PD increases power levels from current standards and boosts them up to 100W. This allows for larger, USB-PD-enabled devices, such as tablets and laptops, to be charged over a USB-C cable without the use of bulky power cables. USB-C cables were designed to be able to handle the increased wattage of USB-PD without overheating or being damaged. USB-PD also enables the freedom of power direction that is not fixed, allowing the host or peripheral device to provide power. With USB-PD, enabled devices are capable of power management that is optimized across multiple peripherals, allowing each device to use only the power it needs. Additional power can be given as it is required for a specific application. This system also provides intelligent and flexible power management through hub communication with the PC. Plus, low-power devices, such as headsets, can negotiate to receive only the power they need. USB-PD specifications have been added to both USB 2.0 and 3.0 adopter agreements.

 

With the introduction of USB-PD, USB continues to prove itself an indispensable interface relevant in today’s continually changing world of technology.

1.      Cat6 Cable: Shielded vs. Unshielded


Category 6 Ethernet cable is designed to provide high speed data rates, but how do you decide between shielded or unshielded? Here, we compare them side by side so you can choose which will work best for your application. Read more.

 

 

2.      10 of the Worst Cabling Nightmares

 

We pride ourselves on our commitment to provide the best connectivity solutions for our customers, helping them to manage their data centers. So it always comes as a shock when we see cabling infrastructure that is a complete nightmare. This post has some of the worst offenders we’ve seen on the web. Read more.

 

 

3.      The Advantages and Disadvantages of Shielded Ethernet Cable

 

When it comes to shielded Ethernet cable, there are pros and cons. This post takes a look at both the good and the bad to help you weigh your options. For example, shielding can offer protection from EMI/RFI but its weight and limited flexibility means it’s not ideal for every application. To help decide if shielded Ethernet cable is right for your installation, read the post.

 

 

4.      75 Ohm vs. 50 Ohm – Coaxial Comparison

 

Ohm may sound like something you’d say while meditating, but when it comes to coaxial cables, it is actually a unit of resistance. Ohms measure the impedance within the cable. Impedance is resistance to the flow of electrical current through a circuit. To see how 75 Ohm and 50 Ohm compare, read our post.

 

 

5.      Good Vibrations: Vibration-Proof USB Connectors


Universal Serial Bus (USB) is one of the most widely used technologies to connect and power devices. One fundamental flaw of USB is its sensitivity to vibration, causing the connector to dislodge. In this post we show you some solutions to keeping your USB connected. Read more.
