| Abstract: | Based on power management IC PM8028,a portable power management system is proposed.The charging and power supply circuit is designed.System state of portable device and software of power management system are divided.System states can switch automatically between each other and the modulation of the power strategy can be achieved through software programming.The system power consumption is reduced.Test results show that the system standby current is small and therefore the standby time of portable device can be extended. |
