The bq500511A is a wireless power
transmitter controller that, when combined with the bq50002A analog
front end (AFE) device, integrates all functions required to create a Qi-compliant or proprietary
5-V transmitter. The bq500511A and bq50002A together provide a compact wireless charger solution. The bq500511A 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 Wireless Power Consortium (WPC) v1.2
specification.
To maximize flexibility in wireless power control applications, Dynamic Power Limiting™
(DPL) is featured on the bq500511A. 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 bq500511A 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 bq500511A is available in a
thermally enhanced 6 mm × 6 mm, 40-pin VQFN package.
