DIO58056

The DIO58056 is a complete constant-current / constant voltage linear charger for single cell Lithium-Ion batteries. 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 for DIO58056 and the charge current and the terminal current can be programmed externally with resistors. The input voltage is up to 36V. When the input supply (wall adapter or USB supply) is removed, the DIO58056 automatically enters a low current state, dropping the battery drain current to less than 1.0µA. The DIO58056 is available in a small packages with DFN2*2-8 and EP-SOIC8. Standard product is Pb-Free.
