The bq500410A device is a free-positioning digital wireless power controller that
integrates all functions required to control wireless power transfer to a WPC compliant receiver.
It is WPC 1.1 ready and designed for 12-V systems but applicable to other supply voltages. The
bq500410A pings the surrounding environment for WPC compliant
devices to be powered, safely engages the device, reads the packet feedback from the powered
device, and manages the power transfer. A charging area of at least 70 mm × 20 mm provides flexible
receiver placement on a transmitter pad. The bq500410A supports both Parasitic Metal Detection
(PMOD) and Foreign Object Detection (FOD) by continuously monitoring the efficiency of the
established power transfer, protecting from power lost due to metal objects misplaced in the
wireless power transfer path. Should any abnormal condition develop during power transfer, the
bq500410A handles it and provides fault indicator outputs. Comprehensive protection features
provide a robust design to protect the system in all receiver placements.
The bq500410A is available in an area-saving 48-pin, 7-mm × 7-mm VQFN package and
operates over a temperature range from –40°C to 110°C.
