USB Power Delivery (USB PD) is an electrical specification developed by the USB Implementers Forum (USB-IF). It’s the latest and greatest in USB power, with the ability to push large amounts of power at high speeds to compatible devices. But what does this mean, and why should you care? Let’s take a look at how it works, what it can do, and why it could be useful to you in your life as an Android user or developer. Read on to learn more about USB Power Delivery! USB Power Delivery: All You Need to Know

What is USB Power Delivery?

USB Power Delivery (USB PD) is a new specification for handling power delivery over the USB Type-C connector. With USB PD, devices can negotiate to deliver higher voltages and currents, enabling faster charging of laptops, phones, and other devices. In addition, USB PD can also be used to provide power to devices that need it, such as powering a display or dock. The USB PD specifications are overseen by the USB Implementers Forum, with support from companies like Apple, Google, Intel, Microsoft, and Texas Instruments.

The 4 Major Features of PD

1. USB PD is a power delivery specification that allows for much higher voltages and currents than standard USB.

2. It can provide up to 100 watts of power, which is enough to charge laptops and other devices that require more power than what standard USB can provide.

3. USB PD also supports fast charging, meaning that devices can be charged more quickly when using a PD-compatible charger.

4. Finally, USB PD has the ability to detect which device it’s plugged into and automatically deliver the correct voltage at either 5V or 20V. The drawbacks? If your device doesn’t support PD then you’ll need an adapter with a Type C connector on one end and your device’s plug on the other end.

Vbus – 5V

The Vbus is the voltage that is supplied by the USB host and is used to power the USB device. The voltage on the Vbus can be different depending on the type of USB port. For example, a standard USB 2.0 port has a Vbus of 5V, while a USB 3.0 port has a Vbus of 5V, 9V, or 12V. When a device is connected to a port, the device draws power from the Vbus to operate. A host is the computer, phone, tablet, etc., that connects via USB to another device such as a printer. Devices may have their own power supply (e.g., battery), or they may need to be plugged into an outlet for power.

For many devices like cameras and mice/keyboards, it doesn’t matter what voltage they are plugged into since they typically don’t draw much current (power).

Vconn – 3.3V, 5V, 12V or 20V

USB Power Delivery (PD) is a relatively new specification that defines a new method of supplying power via USB. In short, it allows for much higher voltages than standard USB, which means more power can be delivered to devices. This can be useful for charging laptops, tablets and other devices that require more power than what a standard USB port can provide. It also reduces the need for proprietary chargers, meaning that if you lose your charger or move to a different country, you won’t have any trouble finding one in the future. There are three PD modes – Control Mode, Host Mode and Device Mode – but only Control Mode is used in smartphones right now.

CC lines

If you’ve ever wondered how USB charging works, you’re not alone. In this post, we’ll explain everything you need to know about USB power delivery. •First, we’ll talk about the CC lines and find out what they do. •Second, we’ll take a look at the role of the OTG cable and see why it’s needed. •Third, we’ll cover some of the common challenges with USB PD as well as how to work around them. Finally, we’ll show you some examples of products that offer USB PD functionality so that you can make an informed decision on whether or not this is something your device needs!

Open Drain Lines (Optional)

Open drain lines are used for high-speed data transfer and can be found in USB 3.0 cables. They allow for two-way communication and provide more power than the standard USB 2.0 cable. However, they are not required for all devices and can be left out if you don’t need the extra speed or power. The USB PD specification also has a 5-volt line that supplies up to 5 amps of current; this is where most of your charging will come from, as it’s only capable of delivering up to 10 watts over its 20 volts.
