The bq500511 is a wireless power transmitter controller that, when combined with the
bq50002 analog front end device, integrates all functions required to create a Qi-compliant or
proprietary 5-V transmitter. The bq500511 and bq50002 together provide a compact wireless charger
solution. The bq500511 pings the surrounding environment for the receiver devices to be powered,
safely engages the device, receives packet communication from the powered device and manages the
power transfer according to WPC v1.2 specification.
To maximize flexibility in wireless power control applications, Dynamic Power Limiting™
(DPL) is featured on the bq500511. DPL enhances user experience by seamlessly optimizing the usage
of power available from limited input supplies.
The system supports 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 field. Should any abnormal condition develop during power
transfer, the bq500511 handles the condition and provides indication outputs. Comprehensive status
and fault monitoring features enable a low cost yet robust Qi-certified wireless power system
The bq500511 is available in a thermally enhanced 6 mm x 6 mm, 40-pin VQFN
