Broadcom Corporation introduced a new multi-standard smartphone power management unit (PMU) that drives Rezence technology into the mainstream while providing compatibility with existing deployed standards.
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.
