* Question
What Three Functions Are Provided by a Power Management System?
* Answer
A power management system generally provides three main functions:
- Power conversion and regulation:Converts the input supply into stable voltage and current levels required by different components.
- Power distribution and sequencing:Routes power to each subsystem and controls the order in which individual power rails turn on and off.
- Power monitoring and protection:Monitors voltage, current, temperature, and battery condition while protecting the system against undervoltage, overvoltage, overcurrent, overheating, and short circuits.
Together, these functions improve energy efficiency, protect electronic components, and ensure reliable system operation.
