PMIC
Power management integrated circuits (power management ICs or PMICs) are integrated circuits (or a system block in a system-on-a-chip device) for managing power requirements of the host system. A PMIC is often included in battery-operated devices such as mobile phones and portable media players. Power ICs are solid state devices that convert heat directly into electricity. They have improved power generation and waste heat recovery techniques, and are used in mobile devices, TVs, and cars.[1] Many devices have multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power to charge their batteries including USB.[2] The term refers to a class of integrated circuits that perform various functions related to power requirements. A PMIC may have one or more of the following functions.
