Abstract

A universal power delivery cable includes a first connector, a second connector, and a power delivery controller. The first connector is used for coupling a host, wherein the host has a power delivery function. The second connector is used for coupling an electronic device. When the first connector is coupled the host, the second connector is coupled the electronic device, and the electronic device does not have the power delivery function, the power delivery controller makes the electronic device imitate to have the power delivery function. After the power delivery controller makes the electronic device imitate to have the power delivery function, the host charges the electronic device according to a specification of the power delivery function and a specification of the electronic device.

First claim

What is claimed is:

1. A universal power delivery cable, comprising:
a first connector coupled to a host wherein the host has a power delivery function:
a second connector coupled to an electronic device; and
a power delivery controller setting the electronic device to communicate with the host according to a specification of the power delivery function when the power delivery controller detects that the electronic device does not have the power delivery function, wherein the power delivery controller is not involved in power transmission between the electronic device and the host when the power delivery controller detects that the electronic device has the power delivery function;
wherein after the power delivery controller sets the electronic device to communicate with the host according to the specification of the power delivery function, the host charges the electronic device according to the specification of the power delivery function and a maximum endurable voltage/current of the electronic device.

2. The universal power delivery cable of claim 1 , wherein the first connector is a type A connector, a type B connector, a mini-A connector, a mini-B connector, a micro-A connector, or a micro-B connector of a Universal Serial Bus (USB).

3. The universal power delivery cable of claim 1 , wherein the second connector is a type A connector, a type B connector, a mini-A connector, a mini-B connector, a micro-A connector, or a micro-B connector of a USB.

4. The universal power delivery cable of claim 1 , wherein the second connector comprises the power delivery controller.

5. The universal power delivery cable of claim 1 , wherein when the first connector is coupled to the host, the second connector is coupled to the electronic device, and the electronic device has the power delivery function, the power delivery controller is disabled.

6. The universal power delivery cable of claim 1 , wherein power delivery controller comprises:
a detection unit detecting whether the electronic device has the power delivery function when the first connector is coupled to the host and the second connector is coupled to the electronic device.

7. A power delivery controller applied to a USB cable, the power delivery controller comprising:
a detection unit detecting whether an electronic device has a power delivery function when a first connector of the USB cable is coupled to a host with the power delivery function, a second connector of the USB cable is coupled to the electronic device, and the power delivery controller is coupled to the second connector;
wherein when the electronic device does not have the power delivery function, the power delivery controller sets the electronic device to communicate with the host according to a specification of the power delivery function, and the host charges the electronic device according to the specification of the power delivery function and a maximum endurable voltage/current of the electronic device after the power delivery controller sets the electronic device to communicate with the host according to the specification of the power delivery function, and when the power delivery controller detects that the electronic device has the power delivery function, the power delivery controller is not involved in power transmission between the electronic device and the host.

8. A USB cable, comprising:
a first connector for coupling to a host with a power delivery function;
a second connector for coupling to an electronic device; and
a power delivery controller controlling the electronic device to make power transmission for charge between the electronic device and the host when the power delivery controller detects that the electronic device is not met a specification of the power delivery function, wherein when the power delivery controller detects that the electronic device is met the specification of the power delivery function, the power delivery controller is not involved in the power transmission for charge between the electronic device and the host;
wherein the power delivery controller controls the electronic device to make the power transmission for charge between the electronic device and the host according to the specification of the power delivery function and a maximum endurable voltage/current of the electronic device,
after the power delivery controller sets the electronic device to communicate with the host according to the specification of the power delivery function.

9. The USB cable of claim 8 , wherein when the power delivery controller detects that the electronic device is not met the specification of the power delivery function, the power delivery controller sets the electronic device to communicate with the host according to the specification of the power delivery function so as to make the power transmission for charge between the electronic device and the host.
