BQ500410A (ACTIVE)

Free Positioning, Qi-Compliant Wireless Power Transmitter Manager

Recommended alternative parts

  • BQ500412  - The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.    The bq500412 is a recommended alternative for 410A because it is simpler and has a lower cost BOM than the 410A.


The bq500410A 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 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 x 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 x 7 mm QFN package and operates over a temperature range from –40°C to 110°C.
