GENERAL DESCRIPTION

FEATURES

specifications. No external sense resistor is needed and no blocking diode is required due to the internal PMOSFET 技 architecture .Thermal feedback regulates the charge k current to limit the die temperature during high power 科 e operation or high ambient temperature .The charge voltage is fixed at 4.2V (ME4056A is 4.34V),and the charge current T can be programmed externally with a single resistor. The 特 e ME4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value 源 rc after the final float voltage is reached. When the input supply (wall adapter or USB supply) is u removed the ME4056 automatically enters a low current state dropping the battery drain current to less than 矽 o 2μA.The ME4056 can be put into shutdown mode reducing S the supply current to 55μA. Other features include Battery temperature monitor, ip under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination.
