Toshiba Collaborating in Development of Wireless Power System IC
Dec. 11, 2012 11:19 PM
Toshiba Corporation (TOKYO:6502) today announced that the company is
collaborating with Hanrim Postec LLC (Hanrim) in the development of
wireless power system ICs. The companies are working on ICs and systems
based on the Qi standard*1 low power spec for mobile devices,
including smartphones and mobile phones, as proposed by the Wireless
Power Consortium*2 (WPC).

Toshiba and Hanrim will enter the mobile market this month with a
non-contact charge system. Toshiba has developed and manufactures the
ICs for the system and Hanrim provides the module.
Demand for smartphones is growing rapidly, and so is their usage, as
more and more people rely on them as a platform for messaging and
accessing the internet. As a result, it is often necessary to charge
smartphones twice a day, sometimes even more, requiring users to carry a
charging cable. This is stimulating demand for a new, cable-free,
non-contact charging system that offers greater convenience and ease of
use.
Toshiba has developed two products to the Qi standard, utilizing
Hanrim's non-contact charging systems. Samples shipments will start from
December.

*1:
|
|
Qi standard
|
|
|
|
An inductive transfer standard for low power applications,
standardized from 0 to 5W.
|
|
*2:
|
|
WPC
|
|
|
|
As of this month, WPC had a total of 137 member companies, clear
recognition that it has established the global de facto standard for
non-contact inductive systems, with companies working on both Qi
standard compatible power transmission and power receiver systems.
|
|
|
|
Toshiba joined WPC in February and has closely studied the standard
toward developing ICs for non-contact charging systems. Hanrim is
also a member.

Features
|
|
1.
|
|
Compliant with WPC Qi standard ver1.0
|
|
|
|
|
|
2.
|
|
Integrated DC-DC converter is used for charge and power feed.
|
|
|
|
For the TB6860WBG power receiver, the DC-DC converter is used to
output voltage. A current capacity output of 1,200mA (max.) ensures
rapid charging.
|
|
|
|
|
|
3.
|
|
Battery charge function included.
|
|
|
|
The TB6860WBG has a power feed mode which feeds power to the charge
system of platform it is charging. It also has a charging mode for
charging the battery directly. If a non-contact charge system is
included in the battery of a mobile device, applying the TB6860WBG
reduces the use of special ICs for charging. It can reduce product
size and cost. The included register can create a unique charging
profile for batteries from multiple companies.
|
|
|
|
|
|
4.
|
|
Charge two devices simultaneously.
|
|
|
|
The TB6865FG can charge two devices simultaneously. While a smart
phone with the "Qi" mark is charged, another mobile device (digital
still camera, mobile game consoles, and so on) with the "Qi" mark
can be charged by placing it on the transmission pad. On charge pad
can support two "Qi" mobile devices. No special cable is required.
