Return to ContentsHow does Wireless Power work? The System provides current to flow through theprimary coil wire (Transmitter coil)Battery(Load)Inductive CouplingReceiver Coil The magnetic field induces a voltage/currentin the secondary coil wire (Receiver coil)System Current passing through the wire generatesa magnetic field (Ampère's Right-Hand-Rule)Transmitter Coil The newly received current can be used tocharge a battery or power a deviceTI Information – Selective Disclosure.

Return to ContentsFunctional Block DiagramTRANSMITTERControllerPowerRECEIVERCoil DriversRectification(DC to AC)(AC to cationAC CurrentDC CurrentControl Signals Power is delivered through shielded coils (like a transformer with separated primary and secondary coils) Before delivering power, the TX sends ‘ping’ signals to detect the RX and start system communication The RX control system tells the TX how much power to send and when to send itTI Information – Selective Disclosure.

WPC v1.1 to v1.2 ConversionTI Information – Selective Disclosure. Battery Management Deep Dive 20169
WPC v1.1 to v1.2 WPC v1.2 is NOT the resonant extension of the spec WPC v1.2 defines requirements for low power and medium power products– WPC Low Power (LP) specification adds a new thermal test for transmitters up to 5 W– WPC approved the Medium Power (MP) specification for receivers and transmitters upto 15 W This document allows LP implementations to take advantage of the MPframework (received power calibration, improved FOD )– This specification has both mandatory and optional features All WPC v1.1 and v1.2 devices are compatibleTI Information – Selective Disclosure.

“To Qi, or not to Qi”WIRELESS POWERCONSORTIUM bq500xxx (TX) and bq51xxx (RX) devices from TI were developed to comply with the Wireless PowerConsortium (WPC) - Qi standard They can also be used for proprietary, non-standard applications Benefits of Qi compliance:– Any Qi-certified RX device can be used with any Qi-certified TX pad or system (e.g. chargers builtinto furniture)– OEM for the handheld device does not have to build their charging pad Some OEMs do not want Qi compliance– Requires that OEM develop both sides of the wireless power system– Allows custom form factors, physical matching between TX device and RX in portable device– Good for non-planar shapes, or applications where the portable device OEM wants to have fullcontrol over the possible charging source (prevent 3rd party “unknown” chargers)– Saves time and cost of Qi certification process, but OEM is responsible for certifying their owndesign including safetyTI Information – Selective Disclosure.
