Samsung unveils Qi 2.2 chip for 50W wireless charging and magnetic chargers
Samsung Semiconductor has introduced the S2MIW06 Power Management Integrated Circuit (PMIC), which is a chip that the company claims is going to "redefine the future of wireless charging." This chipset is indeed intriguing, as it could enable faster wireless charging and new features on Samsung smartphones.
The chip supports wireless charging at up to 50 watts, compared to the current 25 to 45 watts supported by Samsung smartphones. Furthermore, it supports the Qi 2.2 standard. This includes the Extended Power Profile (EPP) that allows for 15-watt charging with non-Samsung chargers. Furthermore, the chipset is compatible with the Magnetic Power Profile (MPP) which supports magnetic chargers and other accessories, similar to Apple's MagSafe on the iPhone 16.
In order to ensure broad compatibility, the Samsung S2MIW06 PMIC has been tested with hundreds of charging pads, including some without Qi certification. With 70KB of integrated flash storage, the chip offers significantly more space for firmware customizations than most competitors. For instance, the firmware allows for a 15% smaller motherboard area that is used for reverse wireless charging.
Samsung Semiconductor has not yet confirmed when the S2MIW06 PMIC will be shipped or in which smartphones this chip will be featured. Rumors suggest that the Samsung Galaxy S25 Ultra is going to support the Qi2 standard, but thus far, Samsung has only confirmed that a Galaxy smartphone with Qi2 support will be released sometime in 2025.
