Broadcom has just announced a brand new power management chip that may ease the compatibility limitations for wireless charging on smartphones and other mobile devices. The BCM59350 supports the three major standards for wireless charging, all while staying cost-effective and the same size as existing solutions that only support one of the standards today.
While bringing all three wireless standards (A4WP, PMA, and WPC) into one chip is an admirable solution in its own right, Broadcom's latest has a more going for it. The BCM59350 supports charging up to 7.5W, allowing for a faster charge than some USB ports or wall chargers. Not only that, but the chip's Boost Mode allows for charging with 50 percent less voltage.
Broadcom also says that the chip can be built into a smartphone's motherboard directly or into a battery cover. While anyone would prefer the former, some manufacturers love to require the customer to spend some extra greenbacks to give their phone wireless charging powers.
Broadcom's new solution has yet to make it to market, and the company is currently sampling it to customers, so it may take a while before we find this chip in any smartphone.
