There are SOT-143 functions included in this PMIC so that you can refer to them. Using Surface Mount, IC management is mounted. There are 4 pins on the supervisor. In order for this IC power to function, the supply voltage (Vsup) cannot be less than 1V. This IC power should be powered by no more than 5.5V volts of supply voltage (Vsup). It also contains ICs of other kinds, such as POWER SUPPLY SUPPORT CIRCUIT, which are included in the power management.
