General  Description
The APL3200 charges a single-cell Li+ battery from both USB and AC adapter sources. It also includes battery to-input power switchover, therefore, the system can be powered directly from the power source rather than from the battery. In its simplest application, the APL3200 doesn’ t need external MOSFET or diodes and accepts input voltages up to 6.5V; however, DC input over-voltage protection up to 18V can be added with a single SOT PFET.
