BQ501210RGCT

产品概述

Wireless power transmitter manager integrates the logic functions required to wirelessly transfer power to a 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 a rail voltage control scheme instead of the traditional frequency control to adjust the amount of power delivered to the receiver. Typically used in smart phones, tablets and other handhelds, point-of-sale devices, custom wireless power applications.

• 12V to 19V input voltage range
• Dynamic power limiting (DPL) allows operation from weak supplies
• Conforms to WPC MP-A5 transmitter type specification
• Enhanced foreign objection detection (FOD) implementation with FOD ping
• Bi-directional communication
• Support fast charge operation with compatible receivers
• Digital demodulation reduces components and simplifies circuitry
• 10 configurable LED modes to indicate charging state and fault status
