(iTers News/Video News) - Wireless charging technology is rapidly becoming a mainstream feature of high-end smartphones like Samsung Electronics Galaxy S5. NXP Semiconductors came up with two different technology standards-based wireless charging chip solutions – A4WP, or Alliance for Wireless Power receiver solution and Qi-based wireless charging transmitter chip solution.

Backed by Wireless Power Consortium, the Qi standards is based on a magnetic inductive electrical power technology, while the A4WP standard is built with a magnetic resonant technology.

NXP’s solution for A4WP standard is a wireless charging receiver chip in what he chip maker said is the world’s smallest ever of its kind. The A4WP has an edge over the Qi standard in its spatial freedom that charges multiple devices at the same time, because it didn't’t call for them to be oriented in any particular direction on a charging pad.

At MWC 2014 held in Barcelona, Spain from Feb. 24 to 27, Rick Dumont, global marketing director with NXP gave a quick demo on NXP’s  Qi and A4WP wireless charging chip solutions.

Its reference designs for 12V and 19V Qi wireless charging transmitter boast a zero standby power, coming built with a NFC, or near field communication technology. The built-in NFC technology allows smart phone users to configure wireless charging pad settings via their NFC-enabled phone or tablet. In addition, the FC-based pairing could be used to trigger “wake up” of the wireless charger, thus enabling zero standby current when not in use.

Other smart features include automatic Bluetooth pairing, or launching applications and web sites when an NFC-enabled phone is put on the charging pad.

Its NXQ1TXA5/A11 5 V wireless charging transmitter are a highly-integrated chip solution that comes complete with a Qi coil, resonant capacitors, and very few external components. It measures less than 2 square centimeters. Mass-production will start in the third quarter.
