SD8017 is a complete constant-current & constant voltage linear charger for single cell
lithium-ion and Lithium-Polymer batteries. Its
SOT-23 package and low external component count make SD8017 ideally suited for portable applications. Furthermore, the SD8017 is specifically designed to work within USB power specification. At the same time, SD8017 can also be used in the standalone lithium-ion and
Lithium-polymer battery chargers.
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 static
at 4.2V, and the charge current can be programmed externally with a single resistor. The SD8017 automatically terminates the charge cycle when the
charge current drops to 1/10th the programmed
value after the final float voltage is reached.
When the input supply (wall adapter or USB supply) is removed, the SD8017 automatically enters a low current stage, dropping the battery drain current to less than 2uA. The SD8017 can be put into shutdown mode, reducing the supply
current to 20uA.
