产品概述
Wireless power transmitter manager conforms to WPC A29 transmitter type specification. It integrates the logic functions required to control wireless power transfer to a single WPC compliant receiver. It is an intelligent device that periodically pings the surrounding environment for available devices to be powered, detects if a foreign metal object is present on the charging pad, monitors all communication from the device being wirelessly powered and adjusts power applied to the transmitter coil per feedback received from the powered device. The IC uses rail voltage control scheme instead of the traditional frequency control to adjust the amount of power delivered to the receiver. Typically used in Qi-certified smart phones, tablets and other handhelds, point-of-sale devices and custom wireless power applications.
- 12V input voltage
- Enhanced foreign objection detection (FOD) implementation with FOD ping
- Low standby power during idle and charge complete
- 10 configurable LED modes to indicate charging state and fault status
- Digital demodulation reduces components and simplifies circuitry
