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 RX1, a second rectifier input terminal RX2, a first bootstrap terminal HSB1, a second bootstrap terminal HSB2. A first and a second bootstrap circuit are coupled to HSB1 and HSB2 to power the rectifier circuit in a regular mode. A over voltage protection (OVP) circuit is coupled between HSB1 and HSB2. The OVP circuit is turned on to connect HSB1 and HSB2 together in an OVP mode.
