If your device needs a mcu anyway, could you not then use part of it to do the job of dedicated IC.
I seen LiPo-charging msp solutions, what about msp wireless power solution?
It of course needs to be able to boot up from wireless power alone if the battery it will charge is completely dead.
The sync rectifier (hbridge maybe?) and the clamping (quad n-mosfet) should not be to hard
