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.

An evaluation kit is available:  DS2710EVKIT
