Power management integrated circuits (PMICs) are an incredibly important product for providing the management of power for practically any kind of electrical item. Effective power management of electricity is vital for creating a reliable, safe, high-performing and valuable bit of equipment.
The type of power management will depend on the power input and you can find various types from places like RS:
Battery-powered management subsystems usually use power conversion ICs which are used to minimize power consumption. Power management subsystems are usually integrated into the electronic system of the product as they are usually portable with size and weight restrictions.
AC input subsystems accepts AC input, filters it and then applies DC voltage to a regulator circuit which maintains a constant DC output.
These subsystems use a power supply which uses DC voltage input and produces DC output voltage. They often use a switch-mode power supply.
Ultra-low voltage input (energy harvesting) captures minute amounts of energy, stores it over time and maintains stored energy as a power source. A power converter is a key component which can work with ultra-low voltage inputs, such as thermal energy, kinetic energy and solar power.
Uses In Driving
The use of PMICs can be seen practically everywhere in today’s technologically advanced age. The automotive industry is somewhere that you now often find PMICs, particularly with the shift towards autonomous driving and the various features that now use this. Additionally, next-generation vehicles will have features like speech recognition and IC-integrated LED front lighting.
Gadgets & Appliances
PMICs are also commonly used in modern consumer gadgets as a way to efficiently manage power and optimize performance. A few examples of common products that use PMICs include smartphones, washing machines, coffee makers, smart TVs and fitness trackers. Many of these devices are also interconnectable through the use of Internet of Things (IoT).
On a larger scale, PMICs are also being used to create what is being called smart cities. These are cities which are connected with public Wi-Fi networks offering access to safety and security, traffic management, waste and water management and more to consumers so that they can better serve citizens.
It is clear that PMICs are heavily used in modern society from small uses on household goods through to a much larger scale on the way in which cities are run. This will only continue in the coming years with the development of new technology and reliance on electronics in so many areas of modern life.
