Overview
APL3202 Li+ Battery Charger with Thermal Regulation Features General Description • Programmable Charge Current Up to 500mA • Charge Status Output Pin • Soft-Start Limits Inrush Current • 4.
2V Charge Termination Voltage with ±1% Accuracy • 45mA Pre-charge Current (R =2K) SET • Thermal Regulation Simplifies Board Design • Enable/Disable Control • Available in a SOT-23-5 Package • Lead Free and Green Devices Available (RoHS Compliant) Applications • Bluetooth Applications • MP3 Players • Cell Phones • Wireless Appliances The APL3202 is a constant-current/constant-voltage linear charger for single cell Li+ batteries.
The APL3202 needs no external MOSFETs or diodes, and accepts input voltages up to 6.
5V.
The small package and low external component counts make the APL3202 an idea part for portable applications.
On-chip thermal regulation protects the APL3202 from excessive temperature and optimizes the board design for compact size and typical thermal conditions.
When the junction temperature reaches the thermal regulation threshold, the charger does not shut down but simply reduces the charge current.
Charge current can be programmed by connecting an external resistor from ISET pin to GND.
Using an external MOSFET to disconnect the resistor from ground shuts down the charger, and reduces the input supply current down to 25µA.
The APL3202 also has the STAT pin to indicate charge status.
The APL3202 is available in a SOT-23-5 package, and operates over the -40°C to +85°C temperature range.
