Automobile / mobile phone brands are supporting multi-mode wireless charging ICs

Core tip : Multi-mode wireless charging chips will become popular. Multi-mode wireless charging chips have attracted more and more attention from the market due to the strong support of smart phones and automobile brands. In addition to the introduction of single-mode products, semiconductor manufacturers are also quick to develop and support Qi, PMA and A4WP wireless charging standards. Die chip solution to attack market opportunities.

Multi-mode wireless charging chips have become impractical. In the face of the controversy among wireless charging standards, smart phone and car brands have considered the advantages and disadvantages of each wireless charging standard, and in order to provide convenience for end consumers, the demand for multi-mode wireless charging chips is more eager, attracting semiconductor manufacturers Layout related product lines to take advantage of market opportunities for smart card smartphones and automotive multi-mode wireless charging applications.

Wang Shiwei, deputy manager of Gaochuang Marketing Department, said that the company reduced the energy consumption of multi-mode solutions by improving the magnetic material of the coil and changing the shape of the antenna using the coil.

Wang Shiwei, associate manager of Gaochuang Marketing Department (Figure 1), said that in addition to the chips of the Wireless Charging Alliance (WPC) camp, which has been introduced by many smartphone manufacturers, Powermat is aiming at the PMA (Power launched by the back cover of iPhone 3 and iPhone 4). Matters Alliance) standard wireless charging chips and their devices have also acquired nearly 50% of the market share, which shows that the PMA and WPC camps have resisted in the wireless charging market. In addition, the future development of the A4WP (All for Wireless Power) camp in the smartphone market The potential should not be underestimated, so smart phone and chip manufacturers have invested in the development of multi-mode wireless charging solutions in order to compete for a bigger business opportunity in the wireless charging market.

It is understood that at present, Texas Instruments (TI), Freescale (Freescale) and other major semiconductor manufacturers are vigorously developing multi-mode wireless charging chip solutions compatible with WPC, PMA and A4WP, of which Texas Instruments has been planned before the end of 2013 Released the first multi-mode wireless charging product; Freescale has also provided samples of dual-mode wireless charging chip solutions compatible with WPC and PMA standards for car smartphone charging docks for dealers to first import reference designs.

Freescale's senior application engineer Huang Yaozong pointed out that the company's chip solution developed for the car's smart phone wireless charging base has already been sampled and is expected to be available by the end of the year.

Freescale senior application engineer Huang Yaozong (Figure 2) revealed that in addition to the dual-mode wireless charging chip, the company will also introduce plans to integrate WPC, PMA and A4WP standard multi-mode wireless charging chip program development, but the specific product release The time has not yet been announced.

In addition to smartphones, major auto brands such as General Motors (GM), Chrysler, Ford and others are planning to introduce dual-mode wireless charging chips compatible with Qi and PMA in the next generation of vehicles in the future. In order to provide a more user-friendly experience for end users, especially GM has mandated that automotive smartphone charging device suppliers must comply with PMA standard specifications, and also encourages chip manufacturers to step up their efforts to support the development of Qi and PMA standard dual-mode wireless charging chips .

EO2 is an Ethernet extender over UTP cable. One EO2 at the network end can support one or multi remote models and their connected IP network devices. This EO2 can transmit over telephone line, Ethernet cable, and twisted pair. It is provided with excellent lightning protection and anti-interference capacity. In the real work environment, the network bandwidth could reach up to 60Mbps. With the Ethernet extended to 750meter, it has enlarged the Ethernet network application area, cutting down the project cost by using Cat5e or Cat6 cable.

N-net EO2 series have POE function, powering remote EO2 transceivers and their connected IP network device, default as a master terminal.
