What is Power Management Unit mean?

The Power Management Unit (PMU) is a microcontroller that governs power functions of digital platforms. This microchip has many similar components to the average computer, including firmware and software, memory, a CPU, input/output functions, timers to measure intervals of time, and analog to digital converters to measure the voltages of the main battery or power source of the computer. The PMU is one of the few items to remain active even when the computer is completely shut down, powered by the backup battery.

For portable computers, the PMU is responsible for coordinating many functions, including:

Monitoring power connections and battery chargesCharging batteries when necessaryControlling power to other integrated circuitsShutting down unnecessary system components when they are left idleControlling sleep and power functions (on and off)Managing the interface for built in keypad and touchpads on portable computersRegulating the real-time clock (RTC) reference
