The bq500211A is a second generation digital wireless power controller that integrates all functions required to control wireless power transfer to a single WPC compliant receiver. It is WPC1.1 compliant and designed for 5-V systems as either a WPC type A5 transmitter with a magnetic positioning guide or as a WPC type A11 transmitter without the magnetic guide. The bq500211A the surrounding environment for WPC compliant devices to be powered, safely engages the device, receives packet communication from the powered device and manages the power transfer. To maximize flexibility in wireless power applications, Dynamic Power Limiting (DPL) is featured on the bq500211A. DPL enhances user experience by seamlessly optimizing the usage of power available from limited input supplies. The bq500211A supports both Foreign Object Detection (FOD) and Parasitic Metal Object Detection (PMOD) by continuously monitoring the efficiency of the established power transfer, protecting from power lost due to metal objects misplaced in the wireless power transfer bath. Should any abnormal condition develop during power transfer, the bq500211A handles it and provides indicator outputs. Comprehensive status and fault monitoring features enable a robust system design.
The bq500211A is available in a 48-pin, 7 mm x 7 mm QFN package and operates over a temperature range from –40°C to 110°C.
