Abstract: Power management and power transfer systems within the transmit and receive portions of an inductive charging system. An inductive charging system includes a transmit coil (105) and a receive coil (110). The receive coil (110) is coupled to inductive charging circuitry (120). The inductive charging circuitry (120) includes circuitry to convert AC output from the receive coil (110) to DC useful to charge a battery (140). The inductive charging circuit is electrically connected to a power management unit (130). The power management unit (130) includes processing circuitry to intelligently determine how to distribute power output from the inductive charging circuit (120) to the battery (140). The charge monitoring circuit (150) is coupled to a ground controller (160). The ground controller (160) couples the charge monitoring circuit (150) to the circuit ground (170) only when the ground controller (160) is in an on state. The ground controller (160) may receive a signal (180) to enter the on state from the inductive charging circuit (120).
