Taiwan peripheral suppliers to benefit from rising wireless charging market demand
Julian Ho, Taipei; Willis Ke, DIGITIMES [Monday 16 October 2017]
As wireless charging is set to gain popularity following the adoption of Qi wireless charging standard of the Wireless Power Consortium (WPC) by both the latest iPhone devices and some Android-based smartphones, Taiwan IC design houses, MCU (microcontroller) suppliers, and protection diodes makers are gearing up for exploring the upcoming huge business opportunities associated with the new charging system, according to industry sources.
The sources said that initially, Qi-certified wireless charging system was mostly applied in Samsung’s Android-based Galaxy series smartphones, but after Apple has also adopted the same cordless charging standard for its iPhone 8, iPhone Plus and iPhone X, many more vendors of Android smartphones have followed suit. This has not only injected growth momentum into the wireless charging market, but also prompted Taiwan makers of wireless charging pads and chips to complete preparations by the end of 2017 to embrace explosive business opportunities in 2018.
Among them, IC designer and MCU supplier Holtek Semiconductor has newly launched 5W and 15W wireless charging pads, both compatible with iPhones. The 5W model has been modularized and passed Qi-certification standard, and the 15W model is expected to win the same certification in the fourth quarter of 2017. In this segment, two more MCU suppliers – Generalplus Technology and Nuvoton Technology – have already had their 15W wireless charging pads certified by WPC.
MCU shipments to see multifold expansion in 2018
In addition, Holtek had also shipped 300,000 MCUs dedicated for wireless charging as of the end of September, and its shipments are expected to break one million units for the whole 2017 and further expand by several folds in 2018 along with the launch of more application devices for wireless…
