TPIC9201PWP

Power Management Integrated Circuits (PMICs) are essentialelectronic components that act as intermediaries between different power delivery orsystem-level power sources, and the various circuits or components in their charge.A combination of circuits and sensors, PMICs are designed to manage power flowwith other secondary systems in a circuit by sensing the input currents andvoltages and setting the output power. Commonly used in manybattery-operated, AC/DC, and other regulated systems, PMICs are one of theessential components used in the development and production of various modernelectronic systems. PMICs also offer protection for higher power systemswithout consuming a lot of power.
