DESCRIPTION
The bq500110 is the industry’s first wireless power dedicated digital controller that integrates most of the logic
functions required to control Wireless Power Transfer in a single channel WPC compliant contactless charging
base station. The bq500110 is an intelligent device that periodically pings the surrounding environment for
available devices to be powered; monitors all communication from the mobile device being wirelessly powered;
adjusts power applied to the transmitter coil per feedback received from the powered device. The bq500110 also
manages fault conditions associated with power transfer and controls the operating modes status indicator. The
bq500110 is also the first wireless power controller with parasitic metal object detection that in real time analyzes
efficiency of the established power transfer and protects itself and the power receiver from excessive power loss
and heat associated with parasitic metal objects placed in the power transfer path.
The bq500110 comes in the area saving 48-pin, 7mm x 7mm QFN package and operates over temperature
range from –40°C to 110°C.
