Power Management (PMIC)(245452)

Power Management definition:

Power management integrated circuits (power management ICs or PMICs or PMU as unit) are integrated circuits for power management. Although PMIC refers to a wide range of chips (or modules in system-on-a-chip devices), 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.

What are the different types of PMICs?

There are mainly four different types of PMICs available in the market-- hardware configurable, software configurable, factory programmed, and user-programmable. Hardware configurable PMICs are similar to discrete devices but with multiple rails integrated into a single chip.
