Broadcom's high performance BCM59350 wireless charging PMU enables automatic selection between specifications from all three leading standards organizations including the Alliance for Wireless Power (A4WP), Power Matters Alliance (PMA) and Wireless Power Consortium (WPC) for OEM flexibility.

A4WP uses resonant technology, called Rezence, that allows consumers to "drop and go," placing multiple devices on a single charging surface without the trouble of accurate positioning or alignment.

Rezence uses Bluetooth Smart technology as a reliable communication channel between the smartphone and charging surface, taking advantage of the wide deployment of Bluetooth in mobile devices and wearables. Leveraging Broadcom's combo connectivity leadership, mobile device manufacturers can easily add multi-standard wireless charging, simplifying development and accelerating time to market for a best-in-class smartphone platform design.

Features:

－ Efficient - up to 88 percent AC to DC efficiency

－ High performance - supports up to 7.5W for faster charge time than standard USB and wall charger

－ Boost mode - Broadcom enables charging performance with 50 percent less voltage

－ Support for automatic selection between standards and single mode operation

－ NFC coexistence - Broadcom's wireless charging design ensures high-quality NFC performance

－ Implementation flexibility - can be designed in a smartphone motherboard or battery cover

－ Small PCB footprint - Broadcom's design supports multiple standards in the same size as a single standard solution

－ Low cost - Broadcom's solution has a cost-effective bill of materials with no external active components, excluding WICED Smart
