Beschreibung
The bq500414Q is an AEC-Q100 qualified free-positioning digital wireless power controller designed for automotive applications. It integrates all functions required to control wireless power transfer to a WPC compliant receiver. It is WPC v1.1 ready and designed for 12-V systems; however, the bq500414Q is applicable to other supply voltages. The bq500414Q pings the surrounding environment for WPC compliant devices to be powered. Once a WPC compliant device is detected, the bq500414Q reads the packet feedback from the powered device and manages the power transfer. A charging area of 70-mm x 20-mm provides flexible receiver placement on a transmitter pad. The bq500414Q supports both Parasitic Metal Object Detection (PMOD) and Foreign Object Detection (FOD) by continuously monitoring the transmitted and received power of the system, protecting the device from over heating. Should any abnormal condition develop during power transfer, the bq500414Q handles it and provides fault indicator outputs. Comprehensive protection features provide a robust design to protect the system in all receiver placements.
The bq500414Q is available in an area saving 48-pin, 7-mm × 7-mm VQFN package and operates over a temperature range from –40°C to 85°C.
