Abstract
Methods and apparatus for over-voltage protection of device inputs are disclosed. An example apparatus to protect a device from an over-voltage condition disclosed herein comprises a switch coupled between a device input and at least one component of the device, and a voltage compensator to pull a control input of the switch to a voltage associated with the device input to open the switch to protect the device component from the over-voltage condition.
