DESCRIPTION
The bq500210 is a second generation Wireless Power dedicated digital controller that integrates the logic
functions required to control Wireless Power Transfer in a single channel WPC compliant contactless charging
base station. The bq500210 is an intelligent device that periodically pings the surrounding environment for
available devices to be powered, monitors all communication from the device being wirelessly powered, and
adjusts power applied to the transmitter coil per feedback received from the powered device. The bq500210 also
manages the fault conditions associated with the power transfer and controls the operating modes status
indicator. The bq500210 supports improved Parasitic Metal Object Detection (PMOD). The controller in real time
analyzes the efficiency of the established power transfer using Rectified Power Packets 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 bq500210 is available in an area saving 48-pin, 7mm x 7mm QFN package and operates over a temperature
range from –40°C to 110°C.
