BATTERY VOLTAGE (V) LTC4063 Standalone Linear Li-Ion Charger with Micropower Low Dropout Linear Regulator Fae Tseru Dpircse Tnoi n Charge Current Programmable upto 1A The LTC 4063 is a standalone linear charger for single cell n Integrated100mA Adjustable Low Dropout Linear lithium-ion batteries with an adjustable low dropout linear Regulator regulator (LDO). The adjustable LDO regulates an output n Charges Single CellLi-Ion Batteries Directly from voltage between 1.2V to 4.2V at up to 100mA load cur- USBPort rent. When the input supply (wall adapter or USB supply) n Preset ChargeV oltage with0.35% Accuracy is removed, the LDO regulates the output voltage without n NoExternal MOSFET,Sense Resistor or Blocking interruption. The battery charger and LDO regulator can DiodeNeeded be enabled individually. n Thermal RegulationMaximizes Charge Rate No external sense resistor or external blocking diode is withoutRisk of Overheating required for charging due to the internal MOSFET archi- n Adjustable LDOOutput Voltage Range: tecture. Internal thermal feedback regulates the charge 1.2V to4.2V current to maintain a constant die temperature during high n Programmable Charge Termination Timer power operation or high ambient temperature conditions. n Programmable Charge Current Detection/Termination The float voltage is fixed at 4.2V and the charge current is n SmartStart Prolongs Battery Life programmed with an external resistor. Charge termination n Charge Status Output methods include minimum charge current or maximum n 35A Charger Quiescent Current in Shutdown time. With power applied, the LTC4063 can be put into n 15A LDO Quiescent Current shutdown mode to reduce the supply current to 35A and n Available in a Low Profile (0.75mm) 10-Lead the battery drain current to less than 2A.
