Battery Charger
Linear Technology introduces the LTC4061, a compact standalone linear 1-cell Li-Ion battery charger with advanced features to improve charging safety, simplify charge termination and status reporting, and prolong battery life. The LTC4061 is equipped with a thermistor interface for temperature qualified charging, an adjustable timer as a backup charge termination, and precision float voltage to prevent overcharging of the cell. A thermal regulation circuit keeps the LTC4061's junction temperature at a safe level. The IC offers four methods for charge termination: user adjustable current and time, external digital control or automatic C/10. The LTC4061 is housed in a 3 × 3 mm DFN package. The LTC4061 can charge both 4.2 and 4.4 V float voltage Li-Ion batteries with ± 0.5% and ± 0.35% accuracy, respectively.
