Surface Mount mounts power management on the wall. 4 pins are present on the power management system. It is recommended that the minimum supply voltage (Vsup) for this IC management should not be less than 550mV volts. This IC power should be powered by no more than 3.6V volts of supply voltage (Vsup). The voltage supervisor requires a power source of 1.2/3.3V volts in order to work correctly.
