Abstract
Apparatus and methods are provided for bootstrap and over voltage protection (OVP) combination clamping. In one embodiment, method is provided to use the same bootstrap capacitors and bootstrap terminals for an over voltage protection circuit. In one embodiment, an integrated circuit for a wireless power receiver comprises a first rectifier input terminal RX, a second rectifier input terminal RX, a first bootstrap terminal HSB, a second bootstrap terminal HSB. A first and a second bootstrap circuit are coupled to HSBand HSBto power the rectifier circuit in a regular mode. A over voltage protection (OVP) circuit is coupled between HSBand HSB. The OVP circuit is turned on to connect HSBand HSBtogether in an OVP mode.
