The bq51222 device is a fully contained wireless power receiver capable of operating in
both the Wireless Power Consortium (WPC) Qi and Power Matters Alliance (PMA) protocols which allows
a wireless power system to work with both inductive charging standards. The bq51222 device provides
a single device power conversion (rectification and regulation) as well as the digital control and
communication for both standards. It also has autonomous detection of protocol and requires no
additional active devices. The bq51222 device complies with the WPC v1.2 and PMA communication
protocol. Together with the WPC or a PMA primary-side controller, the bq51222 device enables a
complete wireless power transfer system for a wireless power supply solution. The receiver allows
for synchronous rectification, regulation and control and communication to all exist in a
market-leading form factor, efficiency, and solution size.
