DS2711/DS2712

Loose-Cell NiMH Chargers

GENERAL DESCRIPTION

PIN CONFIGURATION

The DS2711 and DS2712 are 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 DS2711/DS2712 support series and parallel

topologies, with independent monitoring and control of

each cell. Charging of NiCd chemistry cells is also

supported.
