Abstract

Systems, methods, and circuitries are provided for controlling a microcontroller (MCU) on a per-application basis. A control system includes a microcontroller unit (MCU) including a first application group and a second application group. The first application group includes at least one hardware component not associated with the second application group. The control system includes a power management integrated circuit (PMIC). The PMIC includes monitoring circuitry configured to monitor the first application group to detect a first application group fault condition and monitor the second application group to detect a second application group fault condition. Based on the monitoring, the PMIC provides a first reset signal to the first application group that does not reset the second application group or provides a second reset signal to the second application group that does not reset the first application group.
