DIO58561B

The DIO58561B 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 4.35V for DIO58561B, 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 DIO58561/B automatically enters a low current state, dropping the battery drain current to less than 2.0µA. The DIO58561B is available in a small package with DFN2*2-8. Standard product is Pb-Free.
