ME4064A 800mA Lithium Ion Battery Linear Charger ME4064A General Description ME4064A is a complete constant-current/constant voltage linear charger for single cell lithium-ion batteries. Furthermore the ME4064A is specifically designed to work within USB power specifications. No external sense resistor is needed and no blocking diode is required due to the internal PMOSFET architecture .Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature .The charge voltage is fixed at 4.2V,and the charge current can be programmed externally with a single resistor. The ME4064A automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.
