USB Power Delivery - a New Solution for Universal Charging
HSINCHU, Taiwan --(Business Wire)--
Managing power delivery of up to 100 watts via Universal Serial Bus
(USB) is an important step in enabling a flexible, standardized power
management ecosystem. Etron Technology, Inc. (Taiwan GTSM: 5351) today
announced its latest USB Power Delivery (PD) Controller IC - EJ888,
based on the USB-IF's USB Power Delivery Rev. 1.0 specification, which
enables USB power delivery from 10 watts to 100 watts, and significantly
reduces device charging time. In addition, it makes power delivery more
flexible by adding full bi-directional power that can be renegotiated as
system power needs change with the end-user. EJ888 optimizes user
mobility by allowing data transmission and power delivery to be combined
on a single USB cable. Its advanced power voltage, power stream, and
communication features enable low-power-consumption devices, such as
phones and MP3 players, and even higher-power-consumption appliances,
such as computer monitors and laptops, to be powered via USB.
In a modern life full of various kinds of consumer electronics, power
supply voltage and current demands can vary from one cable, charger, and
battery to another. In recent years, consumer demand for lower-carbon
product and services is growing. USB power delivery is a new
power-supply solution that has the potential to greatly reduce
electronic waste by eliminating proprietary chargers.
"USB Power Delivery will help simplify the lives of consumers by
providing a single-cable for data and power delivery up to 100 watts,"
said Jeff Ravencraft, USB-IF President & COO. "USB-IF member companies
like Etron that incorporate USB PD into products and solutions further
the efforts toward universal charging."
"For early market engagement, Etron's latest USB Power Delivery
Controller IC EJ888 is based on the USB Power Delivery Rev. 1.0
specification. In addition, it supports USB-IF Battery Charging 1.2 for
any portable device. The EJ888 Chip enables higher voltage and current
in order to deliver power up to 100 watts, with 20V to the full 5A, via
USB. Utilizing bi-directional power delivery, EJ188 automatically
detects current sources and sinks, and performs a negotiated handshake
via VBus. It allows users to access simple Plug-and-Charge via USB and
meets the needs of USB PD developers," said Dr. Nicky Lu, Etron
Technology Chairman & CEO.
Micro-USB is the de facto solution for device charging and USB Power
Delivery enables the next significant move toward universal charging.
The European Union now requires cellular phone vendors to use Micro USB
for charging. In addition, the government of the People's Republic of
China is envisioning a significant move toward universal charging based
on USB. Etron is one of the leaders in delivering USB Power Delivery
Controller ICs, including EJ888. Furthermore, the new USB PD market
opportunity has the potential to promote the prosperity of the industry
as a whole.
Etron will display and demonstrate its cutting-edge EJ888 product along
with its comprehensive series of USB 3.0 controller ICs at Booth No.
35116 in South Hall 4 of the Las Vegas Convention Center at CES (News - Alert) 2014
from January 7th to 10th. For more information,
