Fault Status - Accurate Foreign Object Detection Method (FOD)
Prevents Heating of Objects Between Transmitter
and Receiver Coils
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 design.
The bq500511 is available in a thermally enhanced 6 mm x 6 mm, 40-pin VQFN package.
