摘要
A control system for transitioning a DC-DC voltage converter from a buck operational mode to a safe operational mode is provided. A microcontroller performs a first scheduled task including executing first and second applications. The task deadline monitoring application sets a task deadline flag to a first fault value when a time interval associated with performing the first scheduled task is greater than a threshold time interval. The hardware abstraction layer inhibits operation of a disable pin of a watchdog IC when the task deadline flag is equal to the first fault value, which induces the watchdog IC to transition the DC-DC voltage converter to the safe operational mode.
