Wireless Charging Power Management Unit (PMU) Chip

Broadcom's high performance BCM59350 wireless charging power management unit (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. The 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. Broadcom's multi-standard smartphone power management unit drives Rezence™ technology into the mainstream while providing compatibility with existing deployments.

When combined with Broadcom's WICED™ (Wireless Internet Connectivity for Embedded Devices) Smart family of SoCs and software for the charging pad, manufacturers can now build complete end-to-end wireless charging packages.
