GENERAL DESCRIPTION

FEATURES

The DS2714 is ideal for standalone charging of 1 to 4

AA or AAA NiMH “loose” cells. NiCd cells can also be

charged. 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 DS2714 supports a parallel charging topology,

with independent monitoring and control of each cell.
