LC6020 1A Standalone Linear Li-Ion Battery Charge FEATURES DESCRIPTION The LC6020 is a single cell, fully integrated Standalone Capability with no Requirement constant current (CC)/constant voltage (CV) Li-ion of External MOSFET, Sense Resistor or battery charger. Its compact package with Blocking Diode. minimum external components requirement Complete Linear Charger in Compact Package makes the LC6020 ideal for portable applications. for Single Cell Lithium-Ion Batteries Programmable Pre-charge, Fast Charge and No external sense resistor or blocking diode is Termination Current. necessary for the LC6020. Build-in thermal Constant-Current/Constant-Voltage Operation feedback mechanism regulates the charge with Thermal Regulation to Maximize Charge current to control the die temperature during Rate Without Risk of Overheating high power operation or at elevated ambient Charges Single Cell Li-Ion Batteries Directly temperature. from USB Port The LC6020 has a pre-charge function for trickle Preset 4.2V Charge Voltage with 1% Accuracy charging deeply discharged batteries. The fast Automatic Recharge charge current can be programmed by an Charge Status Output Pin external resistor. CV regulation mode is C/10 Charge Termination automatically enabled once the batterys 25 A Supply Current in Shutdown charging curve reaches the constant voltage 2.9V Trickle Charge Threshold portion. The output current then decays and is Soft-Start Limits Inrush Current finally terminated once the charge current drops Available in ESOP8 Package to 1/10 of the programmed value. The LC6020 keeps monitoring the battery voltage and enables a new charge cycle once the voltage drops by 150mV below the CV value. APPLICATIONS Power supply state is constantly monitored and Cellular Telephones, PDAs, MP3 Players the battery drain current is reduced to minimum value automatically when the LC6020 senses a Charging Docks and Cradles lack of input power. In its shutdown mode, the Bluetooth Applications LC6020 can reduce the supply current to less than 25A. A status pin outputs a logic HIGH/LOW to indicate the charging status and the presence of power supply. Other features include charge current monitor, under-voltage lockout.
