Everything in an AMR runs from one battery, and power management is the layer between that battery and every rail in the system. Power management includes converting battery voltages to different subsystem levels, keeping the battery healthy, and disconnect or clamp when faults occur.
While some components serve a specific subsystem, others like LDOs and PMICs supply rails across the whole platform and therefore applicable to virtually any function.
