ChipSourceTek ME4064A
ME4064A is a complete constant-current/constant ●Protection of battery cell reverse connection voltage linear charger for single cell lithium-ion ●No MOSFET sense resistor or blocking diode batteries. The ME4064A automatically 源 rc terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final u float voltage is reached. Furthermore the ME4064A is specifically required designed to work within USB power specifications.| Part No. | ME4064A |

GENERAL DESCRIPTION
FEATURES
●Complete Linear Charger in ThinSOT Package for No external sense resistor is needed and no Single Cell Lithium-Ion Batteries blocking diode is required due to the internal PMOSFET architecture .Thermal feedback regulates 技 the charge current to limit the die temperature during k high power operation or high ambient 科 e temperature .The charge voltage is fixed at 4.2V,and T the charge current can be programmed externally with 特 e a single resistor. 矽 o When the input supply (wall adapter or USB supply) is removed the ME4064A automatically enters a low S current state dropping the battery drain current to less ip than 2μA.The ME4064A can be put into shutdown mode reducing the supply current to 55μA. Ch Other features include charge current monitor,●Constant-Current/Constant-Voltage operation with thermal regulation to maximize Rate Without risk of overheating.
● Preset 4.2V charge voltage with ±1% accuracy
● Automatic Recharge
●Charges Single Cell Li-Ion Ba...
