  "textContent": "A system-on-a-chip (SoC) is designed to operate within optimal voltage and frequency ranges. If an SoC is provided power outside of the optimal voltage range, the SoC can be placed in a high-stress state, exposing the chip to a security attack. Embodiments of the present systems and method limit the minimum and maximum voltage supplied to an SoC from a power management integrated circuit (PMIC). Embodiments can also track a number of requests to provide power outside of the optimal range and can signal a warning of repeated attempts to take an SoC outside of the SoC's optimal range, which may be indicative of a malicious attack on the system.",
