DS2712Z+

The DS2712Z+ is a loose-cell NiMH charger in 16 pin NSOIC package. This device is ideal for in-system or stand-alone charging of 1 or 2 AA or AAA NiMH “loose” cells. Temperature, voltage and charge time are monitored to provide proper fast-charging control algorithms for nickel metal hydride (NiMH) batteries. Battery tests are included to detect defective or inappropriate cells such as alkaline primary batteries. It support series and parallel topologies with independent monitoring and control of each cell. DS2712 series configuration supports one or two-slot stand-alone and one or two cell in-system chargers. In parallel configuration, the device supports two slot stand-alone chargers.
