Figure 4. Full-Featured Circuit. Overvoltage protection MOSFET (Q2) on DC withstands up to 18V from the AC adapter, but disables
charging at inputs over 6.2V. Output switch-over MOSFET (Q3) disconnects the battery from the system load when input power is
applied. The input can power the system through D1, D2, Q1, and Q2 when either USB or AC power is present.
