What is Power Delivery (PD) and how does it relate to USB-C?
Power Delivery (PD) is a technology that enables the delivery of higher power levels over USB connections, making it possible to charge larger devices such as laptops and tablets quickly and efficiently. It is an extension of the USB protocol that allows for the negotiation of power delivery between a power source, such as a wall adapter or power bank, and a device, such as a laptop or smartphone. This negotiation ensures that the power source can supply the required amount of power to the device, while also preventing damage to the device from excessive power.
The relationship between Power Delivery and USB-C is that USB-C is the physical connector that can be used to deliver Power Delivery. However, not all USB-C ports or cables support Power Delivery. To take advantage of Power Delivery, both the power source and the device must support the PD protocol, and the USB-C cable must be capable of carrying the higher power levels. This means that even if a device has a USB-C port, it may not be able to take advantage of Power Delivery unless it is specifically designed to do so. As a result, it is essential to check the specifications of both the power source and the device to ensure that they are compatible and can support Power Delivery.
How does Power Delivery (PD) work over USB-C?
Power Delivery over USB-C works by using a communication protocol to negotiate the amount of power that can be delivered from the power source to the device. This negotiation takes place over the USB-C connection and involves the exchange of messages between the power source and the device. The power source advertises its capabilities, such as the amount of power it can supply, and the device requests the amount of power it needs. If the power source can supply the requested amount of power, it will do so, and the device will be able to charge at a higher rate.
The actual delivery of power over USB-C involves the use of dedicated power paths within the cable. These power paths are designed to carry higher currents than traditional USB cables, making it possible to deliver more power to the device. The power source will typically use a chip to control the power delivery and ensure that the device is receiving the correct amount of power. The device will also have a chip that manages the power delivery and ensures that it is receiving the correct amount of power. This communication and control ensure that the power delivery is safe and efficient, preventing damage to the device or the power source.
