The is a free positioning Power Transmitter Manager integrates all functions required to control wireless power delivery to a single WPC1.1 compliant receiver. The device surrounding environment for WPC compliant devices to be powered, safely engages the device, receives packet communication from the powered device and manages the power transfer according to WPC1.1 specification. To maximize flexibility in wireless power control applications, dynamic power limiting DPL is featured on the device when used with an optional boost converter from a 5V input. Dynamic power limiting enhances user experience by seamlessly optimizing the usage of power available from limited input supplies. The device supports both Foreign Object Detection and enhanced parasitic metal object detection for legacy product 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.
