Product Summary

The ds2712 is a loose cell nimh charger. The DS2712 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. The ds2712 support series and parallel topologies, with independent monitoring and control of each cell. Charging of NiCd chemistry cells is also supported. Applications are: (1)desktop/stand-alone chargers (aaa/aa); (2)digital still cameras; (3)music players; (4)games; (5)toys.
