Claim 19:
20. An apparatus for protecting one or more components of a wireless power receiver, the components comprising at least one transistor gate, the apparatus comprising:
a safety controller configured to provide at least one fault signal to indicate a fault in one or more components of the receiver, wherein the at least one fault signal comprises a hardware enable signal;
a power controller configured to provide at least one control signal to control a state of the at least one transistor gate, wherein the at least one control signal comprises at least one pre-pulse width modulation (PRE-PWM) signal;
a pre-drive circuit coupled to the safety controller and the power controller, configured to:
receive the at least one fault signal from the safety controller;
receive the at least one control signal from the power controller; and
transmit the at least one control signal; and

a post-driver circuit, coupled to the pre-drive circuit, configured to:
receive the at least one control signal from the pre-drive circuit; and
transmit at least one post-PWM (POST-PWM) signal to the at least one transistor gate.
