Product Description
Mfr#:
LP4057
Brand: LowPowerSemi
600mA Standalone Linear Li-Ion Battery Charger
General Description:
The LP4057 is a complete constant-current/constant- voltage
linear charger for single cell lithium-ion batteries. Its package
and low external component count make the LP4057 ideally
suited for portable applications. Furthermore, the LP4057 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 MOSFET 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 LP4057 automatically terminates the charge cycle
when the charge current drops to 1.5/10th the programmed
value after the final float voltage is reached. When the input
supply (wall adapter or USB supply) is removed, the LP4057
automatically enters a low current state, dropping the battery
drain current to less than 1µA. Other features include charge
current monitor, automatic recharge and a status pin to indicate
charge termination and the presence of an input voltage
