Broadcom Chip Supports Multiple Wireless Charging Standards
Broadcom today announced a new system-on-a-chip that supports all of the wireless charging standards, including the Alliance for Wireless Power, the Power Matters Alliance, and the Wireless Power Consortium. The multi-standard smartphone power management unit (PMU) works automatically with all the standards, allowing device makers to support them all in a single piece of hardware. According to Broadcom, the BCM59350 is efficient; supports up to 7.5W for faster charge time; includes NFC; and is inexpensive. The BCM59350 is already sampling to select customers and will reach volume production later this year. In February, the PMA and A4WP joined together and together use the Rezence brand name. With the PMA and A4WP efforts combined, the Wireless Power Consortium and its Qi standard stand alone. Each uses magnetic induction to pass an electrical charge from a pad to a properly-equipped device. Variations in the standards prevent a Rezence-compliant device, for example, from charging on a Qi-based pad and vice versa. The new chip from Broadcom will solve that issue until the industry settles on a single standard.
PMA and A4WP Rebrand As the AirFuel Alliance
The Power Matters Alliance and Alliance for Wireless Power today announced plans to fully merge organizations under the AirFuel Alliance brand. The standard-bearers for wireless charging agreed to work together earlier this year, and today's rebranding is the final step in the process of creating a single consortium committed to improving the standards for and experience of wireless charging.
LG Debuts Wireless Charging Pad
LG Innotek today announced the Quick Wireless Charging Pad, a way for smartphone owners to rapidly charge their mobile devices. The Quick Wireless Charging Pad relies on the Wireless Power Consortium, or Qi, wireless charging spec and supplies 15 W of power.
A4WP and PMA Agree to Fully Merge
The Alliance for Wireless Power and the Power Matters Alliance today agreed to merge operations. In February 2014, these same two organizations agreed to work together to create a single wireless charging standard.
