3.5 PMIC (MT6318)

Power management is one of the most important functions in this PMIC. The power

management function applies proper management procedures and control functions to the
mobile handset’s battery, charger, and power supply. More specifically, the management
criterion is to provide power to the mobile phone while extending the standby/active time as
long as possible.

The block diagram implemented in PMIC is shown further below to describe the relationships

between different states.
