Abstract
A power supply module implemented within a first device and including a voltage regulator and an authentication module. The voltage regulator receives power from a power source and supplies the power to devices within the first device. The power source is separate from the power supply module. The authentication module includes a regulator module and a generation module. The regulator module controls operation of the voltage regulator based on operation in one of multiple operating modes. The generation module: receives an authentication request signal from a host device; in response to the authentication request signal, transmits an authentication response signal to the host device; and receives a notification signal from the host device based on the authentication response signal. The notification signal indicates whether the power supply module is an authorized device. The regulator module is configured to transition between the operating modes based on the notification signal.
