Power Sequencing
A power management integrated circuit (PMIC) is an integrated circuit for power management. Although it is a wide range of chip types, most include several DC/DC converters or their control part. A PMIC is often included in battery-operated devices (such as mobile phone, portable media players) and embedded devices (such as routers) to decrease the amount of space required. Overview The term PMIC 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: * DC-to-DC conversion * Battery charging * Power-source selection * Voltage scaling * Power sequencing * Miscellaneous functions Power management ICs are solid-state devices that control the flow and direction of electrical power. Many electrical devices use multiple internal voltages (e.g., 5 V, 3.3 V, 1.8 V, etc.) and sources of external power (e.g., wall outlet, battery, etc.), meaning that the power design of the dev ...
