Abstract:
1. A power management system comprising: a state machine, capable of transitioning the power management system to a safe state when an input signal and/or an output signal from a component of the power management system indicates occurrence of an error in the components, wherein the state machine is operable to transition the power management system into a start charge pump state wherein an activation voltage is applied to a charge pump associated with the power managements system when no errors are detected during a startup state, transition the power management system into a start system regulators state wherein a voltage regulator associated with the power management system is initiated when no errors are detected during the start charge pump state, and transition the power management system into a power on state wherein an activation voltage is applied to the component of the power management system when no errors are detected during the start system regulators state.
