Power. Every device needs it. Managing it properly can make all the difference between a device people enjoy using and one that is more hassle than it is worth. What happens between the battery and the processor is the job of the power management integrated circuit (PMIC).

Why are PMICs gaining so much attention? Increased power subsystem complexity and, paradoxically, reduced power consumption is causing PMICs to be far more intelligent. In a simpler day of digital design, chips ran on one power supply – Vdd on schematics. Mixed signal requirements including analog inputs, high voltage peripheral drivers, and varying stages of digital logic gave rise to multiple power supplies to a single integrated chip.
