The adoption of wireless charging is driven by the need for convenience, safety, and durability. The race is on to develop the next big thing in wireless power!

From mobile devices to electric vehicles, the potential applications to adopt wireless power are endless. As we move towards a more connected, cordless, and a battery-less/battery-free world, wireless power technology will become increasingly important.

Traditional charging cables have several issues – they tangle, break, and get old over time. Furthermore, the need for multiple cables for different devices leads to clutter, inefficiency and environmentally unfriendly situation.

Adoption of Wireless Charging is still in its nascent stage; it is expected to continue advancing steadily, increasing its efficiency levels, bringing it closer to traditional (wired) power/charging methods, and helping to address some key pain points and use cases. It also reduces wear and tear on devices (from a ports/connectors perspective), allows for completely sealed devices, and provides many other benefits associated with wireless charging, including the convenience of charging wirelessly and seamlessly

While wireless charging technology has seen significant improvements, key challenges remain in terms of compatibility (across and beyond an application), efficiency levels, power transfer speed, and safety. The latest advancements, including Samsung’s PMIC, S2MIW06, address these concerns and push the industry forward.

• Enhanced Efficiency: Features power transfer efficiency of up to 98%, minimizing energy loss and heat generation.
• Optimized Communication: Utilizes an in-band communication method to relay critical charging data between Tx and Rx without requiring additional chips.
• Space-Saving Design: Built-in ASK demodulation filters reduce PCB footprint by approximately 15%.
• Dual-Mode Functionality: Enables wireless power sharing, allowing smartphones to charge other devices with its transceiver solution.
• Broad Compatibility: Supports BPP, EPP, and MPP standards within Qi and is tested with a wide range of wireless power charging pads.

Ensuring Compatibility in Wireless Charging

Samsung’s PMIC, S2MIW06 has broad compatibility. But what does that imply? The PMIC can be utilized in all profiles which come with the Qi standard Broadly, the Qi standard is categorized into three power profiles:

• Baseline Power Profile (BPP): Introduced in Qi v1.0, this profile supports up to 5W of power transfer and enables basic one-way communication between the transmitter (Tx) and receiver (Rx) via Amplitude Shift Keying (ASK).
• Extended Power Profile (EPP): With power delivery up to 15W, EPP allows for two-way communication, enabling fast charging and with enhanced safety measures, including debris/foreign-object detection.
• Magnetic Power Profile (MPP): This profile incorporates magnetic alignment for improved usability and stability, currently supporting wireless charging up to 25W levels.

By supporting all Qi profiles and offering high-speed charging capabilities, the S2MIW06 PMIC ensures that devices equipped with this chip can work seamlessly with a wide range of wireless chargers, enhancing user convenience and compatibility across different brands and models
