Wireless charging market bloom, the Newyea microelectronic chip attract attentions

Wireless charging is no longer a novelty, thanks to the widespread adoption of wireless charging in mobile phones in recent years.Take Apple for example, since the release of iPhone 8 series in 2018, Apple has entered the wireless charging market. So far, it has launched more than a dozen iphones with wireless charging function, and the mobile phone market stock is about 1 billion units. In particular, MagSafe wireless charging technology for iPhone 12/13 series is favored by some users.
From the current development trend, the future of wireless charging application scenarios will be more and more, and as the core components of wireless charging accessories products, master chip is naturally become the focus of the industry, but also the focus of the semiconductor factory layout.Today, I would like to share with you the current mainstream wireless charging chip manufacturers and corresponding solutions on the market.

Type of Tx wireless charging and transmitting scheme

Wireless charging transmitter Tx (Transport) for short.From the perspective of chip integration, the current mainstream wireless charging and transmitting schemes in the market can be roughly divided into SoC scheme, MCU master control + power full-bridge scheme and wireless charging mobile power scheme.

1. Wireless charging SoC chip scheme

SoC stands for System on a chip, which refers to the integration of a complete System on a single chip.At present, the relatively common DEFINITION of SoC solution is: SoC is the integration of master control and driver.But there are voices that this is not accurate, master control, driver, MOS is the real SoC.The soCs described below include both types.

According to the incomplete statistics of charge head network, at present, a total of 24 original chip manufacturers including Sinpage Microelectronics have launched SoC type wireless charge emission, and there are as many as 91 chip models.In terms of output power, in addition to the common BPP 5W, Samsung 10W, EPP 15W, there are more power 20W, 30W, 50W, 100W and other levels.

2. MCU master control + intelligent power full bridge scheme

Different from SoC, the PowerStage intelligent power full bridge of this kind of scheme integrates the driver and MOS into one, and they have different advantages respectively.For this scheme, we can think of it as a transition from MCU to fully integrated SoC.

According to incomplete statistics of charging head network, 13 manufacturers have launched 50 chip schemes for MCU master control +PowerStage intelligent power full bridge scheme.Among them, New page microelectronics provides seven different models of chips, for wireless charging manufacturers to provide a complete technical solution.

Newyea new page microelectronics

Newyea Microelectronics in the field of small and medium power wireless charging, has been keeping the momentum of progress, launched 7 kinds of wireless charging chip solutions, in addition to the conventional Qi wireless charging standard, and support 300W wireless charging medium power solutions.

Micro NY7503S + SY03 new page

NY7503S wireless charging transmitter chip, it is a 10W highly integrated wireless power transmitter IC, compatible with WPC Qi 1.2.4 specification, efficiency up to 80%, support various protection functions such as FOD.

SY03 is a highly integrated analog front end for wireless charging transmitter, which contains all the analog components needed to implement a TRANSMITTER conforming to the WPC standard.SY03 integrates a full-bridge power driver, MOSFET, current detection amplifier, bootstrap circuit, communication demodulator, linear regulator and protection circuit.

SY03 can be used in conjunction with transmitter controllers to create high-performance wireless power transmitters that comply with WPC V1.2.4 Extended Power Profile (EPP) and Baseline Power Profile (BPP).Once an EPP receiver is detected, the transmitter will provide up to 15W of output power.If a BPP receiver is present, the transmitter only provides up to 5W of output power.

Application Cases:

Green Link desktop wireless charger

At present, only mobile phones as the center, the statistics of the mainstream wireless charging chip scheme in the market, the number of nearly 150, for mobile phone wireless charging accessories development provides a rich choice.At the same time, it can be seen that mobile phone wireless charging and transmitting chips are also moving towards the integrated route, and highly integrated SoC has become the main stream.

In the future, wireless charging will be applied in more and more scenarios. Mobile phones, headphones, tablets, keyboards, mice, electric toothbrushes, robots and many other product areas are expected to popularize wireless charging technology.The increase of wireless charging products will inevitably lead to an increase in the shipment of corresponding accessories, which also creates a favorable external environment for the development of wireless charging chips.
