Managing the power delivery ability of up to 100 watts via the Universal Serial Bus (USB) is really an important step in enabling a standard, flexible, and standardized power management ecosystem.
The Etron Technology Inc. has recently announced their latest USB Power Delivery (PD) Controller IC – EJ888, which is based on the USB-IF’s USB Power Delivery Rev. 1.0 specification, which also enables the USB power delivery from 10 watts to the 100 watts, and it significantly reduces the device charging time. In addition to it, it also makes the power delivery mode more flexible by adding some full bi-directional power which can easily be renegotiated as the system power needs change with the end-user.

The EJ888 model optimizes the user mobility by allowing the data transmission and the power delivery to be combined on just a single USB cable. It’s more advanced power voltage, the power stream, and the communication features also enable some low-power-consumption devices, such as the phones and the MP3 players and even some higher-power-consumption appliances, such as the computer monitors and the laptops, to be powered via the cable.

In the modern life, which is usually full of various kinds of consumer electronics, the power supply voltage, and the current demands can always vary from one cable, a charger, and a battery to another. In the recent years, the consumer demand for the lower-carbon products and the services is also growing. USB power delivery is a brand new power-supply solution which has the potential to greatly reduce the electronic waste by automatically eliminating the proprietary chargers.
