Surface Mount mounts power management on the wall. The pins of the power management system count 3. Normally, the supply voltage (Vsup) for this PMIC should not be lower than 1V. The supply voltage (Vsup) should not exceed 6V volts in this IC power. It also contains ICs of other kinds, such as POWER SUPPLY SUPPORT CIRCUIT, which are included in the power management. If you want to work with PMIC chip, you will need to supply PMIC chip with a temperature at least of 3.5μA.
