As you may know the Power Always voltages, which are always and constantly present on circuits, are very important voltages in circuits.
In this video which is the second part of reading and understanding schematics, we are going to analyze power always voltages 3.3v, 5v, 1.8v and 1v ALW_PWR (power always).
We will also explain and analyze the components that provide these voltage: PU401 (3 volt), PU402 (5 volt), PU601 (1.8 volt) PU601 (1 volt) and analyze all their pins and their obligations in circuit.
