Transmitter integrates logic functions to wirelessly transfer power to WPC-compatible receiver

Available from Mouser, Texas Instruments bq501210 wireless power transmitter manager integrates the logic functions required to wirelessly transfer power to a WPC-compatible receiver. The device has the capability of delivering up to 15W. The device is a WPC v1.2 compatible device. This device is an intelligent device that periodically pings the surrounding environment for available devices to be powered and detects if a foreign metal object is present on the charging pad. It also 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 device manages the fault conditions associated with the power transfer and controls the operating mode status indicator. The device uses a rail voltage control scheme instead of the traditional frequency control to adjust the amount of power delivered to the receiver.
