产品概述

Wireless power controller for WPC TX A5 or A11. It integrates all functions required to control wireless power delivery to a single WPC1.1 compliant receiver. The IC pings the 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. It handles any abnormal condition development during power transfer and provides indicator outputs. Comprehensive status and fault monitoring features enable a low cost yet robust, Qi certified wireless power system design. Typically used in smart phones and other handhelds, car and other vehicle accessories.

• Lowest device count for full WPC1.1 5V solution
• Improved foreign object detection (FOD) method
• Permits X7R type resonant capacitors for reduced cost
• Dynamic Power Limiting™ for USB and limited power source operation
• Digital demodulation removes need for external filter circuitry
• LED indication of charging state and fault status
