As we all know, Apple is good at setting standards and launching various certifications. We were informed that Apple will open 15W MagSafe magnetic wireless charging certification in the near future, and major third-party manufacturers have been looking forward to this for a long time.
Apple announced: "We are pleased to announce the new Apple MagSafe charger module! This module provides secure wireless charging up to 15W and can be integrated in MFi accessories to wirelessly charge Apple devices through MagSafe. MFi license holders can now submit product plans that include this module, and order samples and mass production from MFi authorized dealers. Log in to the authorized dealer’s website for prices. Log in to the authorized dealer's website to find out the price. Accessories that integrate this module and complete MFi certification will be able to use the Made for MagSafe badge on product packaging and communications. "
If a brand that has passed MFI certification wants to launch a 15W MagSafe magnetic wireless charger, then the brand can submit a product plan that includes a 15W MagSafe charging module, and order samples and production from authorized MFi dealers.
Focuses consults a third-party testing laboratory, and the procedure for MFi certification is shown in the figure above.
It is worth mentioning that after third-party brand products have passed MFi certification and integrated Apple’s 15W MagSafe charging module, the “Made for MagSafe” logo can be added to the packaging and promotion. Generally speaking, the "MFM" logo will enhance the public consumers' evaluation of these brands.
Apple 15W MagSafe charging module details Regarding the Apple-certified MagSafe magnetic charging module, we has disassembled the sample.
The module is in the shape of a flat round pie, the front is pure white, and the back is encapsulated with a metal shielding cover. The overall look is tight. At the same time, this wireless charger module also reserves five pads for connecting power and communication cables, namely VBUS, V+, V-, CC, and GND.
According to the communication definition diagram, it can be seen that the MagSafe wireless charging module adopts the standard USB PD communication method, the power supply is 9V voltage standard, and it also has a USB2.0 D+D- data cable core. CC wire core is the most critical, used for PD charger communication handshake, of course, it also has a ground wire.
As a component sold separately to third-party manufacturers, the module pays more attention to the integrity of the function, so it integrates a complete voltage regulation power supply circuit, wireless charging control and drive circuit. When developing related accessories, third-party manufacturers only need to match an adapter of 20W or more and connect the positive and negative power supply to realize 15W wireless fast charging for the iPhone 12 series. The application is very simple.
Focuses makes a summary:
Judging from the current development trend, Apple's determination to promote the MagSafe ecosystem is quite firm. In addition to MagSafe magnetic wireless charging, Apple's official website also has a variety of ecological products such as magnetic mobile phone cases, magnetic card holders, and magnetic holders. The MFM certification will be officially opened soon, let us look forward to the appearance of more excellent magnetic products!
