Abstract: Various embodiments are directed to maintaining operational stability for a system on a chip (SOC). A power management integrated circuit (PMIC) includes comparator circuits operative to monitor a current level on a power supply rail of the SOC. An interrupt management component may create an interrupt when the monitored current level crosses the threshold setting. The interrupt may indicate whether the current level has crossed the threshold setting into or out of excessive current levels. A microcontroller on the SOC coupled with the PMIC via a low latency interrupt channel over a communication interface may receive and interpret the interrupt. The microcontroller may be operative to change an operating point of one or more components on the SOC in response to the interrupt to alleviate an overcurrent situation.
