BQ500211ARGZT

WIRELESS POWER TRANSMITTER, VQFN-48.

The BQ500211ARGZT is a second generation Digital Wireless Power Controller that integrates all functions required to control wireless power transfer to a single WPC compliant receiver. It is WPC1.1 compliant and designed for 5V systems as either a WPC type A5 transmitter with a magnetic positioning guide or as a WPC type A11 transmitter without the magnetic guide. The bq500211A pings the surrounding environment for WPC compliant devices to be powered, safely engages the device, receives packet communication from the powered device and manages the power transfer. To maximize flexibility in wireless power applications, Dynamic Power Limiting™ (DPL) is featured on the bq500211A. The bq500211A supports both Foreign Object Detection (FOD) and Parasitic Metal Object Detection (PMOD) by continuously monitoring the efficiency of the established power transfer, protecting from power lost due to metal objects misplaced in the wireless power transfer bath.
