DS2710 fiche technique
Rev 0; 4/08
Single-Cell NiMH Charger
General Description
The DS2710 is ideal for in-system charging of single-cell
nickel metal hydride (NiMH) cells for low-current
portable applications. Inputs to the DS2710 include USB
voltage sources and 5V regulated adapters.
Temperature, voltage, and charge time are monitored to
provide proper fast-charging control algorithms for
single-cell NiMH or nickel cadmium (NiCd) batteries.
The DS2710 includes battery tests to detect defective or
inappropriate cells such as alkaline primary batteries.
