Power management ICs (PMICs) are integrated circuits that include multiple power rails and power management functions within a single chip. PMICs are frequently used to power small, battery-operated devices since the integration of multiple functions into a single chip results in more efficient use of space and system power. Functions commonly integrated into a PMIC include voltage converters and regulators, battery chargers, battery fuel gauges, LED drivers, real-time clocks, power sequencers, and power control.

Low-power PMICs provide the high-efficiency and compact form factors needed for space-constrained applications such as wearables, hearables, sensors, and IoT devices. High-performance PMICs maximize performance per watt while increasing system efficiency for computationally intensive platforms such as systems-on-chip (SoCs), FPGAs, and application processors.
