Anpec Electronics APL3200
The APL3200 charges a single-cell Li+ battery from both USB and AC adapter sources. It also includes batteryto-input power switchover, therefore, the system can be powered directly from the power source rather than from the battery. When the APL3200 thermal limit is reached, the charger does not shut down but simply reduces charging current.| Part No. | APL3200 |

GENERAL DESCRIPTION
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. On-chip thermal limiting simplifies PC board layout and allows optimum charging rate without the thermal limits imposed by worst-case battery and input voltage. Ambient or battery temperature can be monitored with an external thermistor. When the temperature is out of range, charging pauses.
