Section 1: Charging Circuit Input The primary input to the charging system is the 5V supply provided through the charging port . Let’s break this down: 1.1 Input Voltage (5V) The charging port, marked as "C/C Positive 5V," is where the external power adapter connects. This 5V input is the universal charging voltage for most mobile devices, balancing efficiency and compatibility with USB standards . 1.2 Protection Circuit Before entering the critical components, the input passes through a 200-ohm resistor . This resistor serves multiple purposes: Current Limiting : Limits the inrush current when the charger is connected, protecting downstream components. Transient Protection : Reduces the effects of voltage spikes caused by fluctuating input. 1.3 Voltage Regulation The input voltage is further processed by the charging IC (Integrated Circuit), which ensures the followi…
