r· Accurate BATT Regulation Voltage· Programmable DC Charging Current· Selectable USB Charging Current (Either 100mAor 500mA)· Thermal Regulation for Simplified Board Design· Input Protection Up to 18V· Soft-Start· External Thermistor Monitoring· Charge Shutdown Control· Charge Status Outputs· DC and USB Power-OK Indicators· Small, High Power QFN5x5-16 and TQFN4x4-16Packages· Lead Free and Green Devices Available (RoHS Compliant)The APL3200 charges a single-cell Li+ battery from bothUSB and AC adapter sources. It also includes batteryto-inputpower switchover, therefore, the system can bepowered directly from the power source rather than fromthe battery.In its simplest application, the APL3200 doesn’t needexternal MOSFET or diodes and accepts input voltagesup to 6.5V; however, DC input over-voltage protection upto 18V can be added with a single SOT PFET.On-chip thermal limiting simplifies PC board layout andallows optimum charging rate without the thermallimits imposed by worst-case battery and input voltage.When the APL3200 thermal limit is reached, the chargerdoes not shut down but simply reduces charging current.Ambient or battery temperature can be monitored withan external thermistor. When the temperature is out ofrange, charging pauses.Other features include STAT 1 and STAT 2 outputsindicating various charge status. DC power-OK (DCOK),USB power-OK (UOK), and poweron (PON) outputsindicate when valid power is present. These outputs drivelogic or power-selection MOSFETs to disconnect thecharging sources from the load and to protect the APL3200from overvoltage. The APL3200 doesn’t contain logic forcommunication with the USB host. It must receiveinstructions from a local microcontroller. The APL3200is available in 16-pin 5mmx5mm QFN and 4mmx4mmTQFN packages and operates over the -40°C to +85°Ctemperature range.F

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; whichare fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020C forMSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogenfree (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm byweight).
