GENERAL DESCRIPTION
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.
FEATURES
Charges 1 to 4 NiMH Cells
Detects and Avoids Charging Alkaline Cells
Pre-Charges Deeply Depleted Cells
Fast Charges NiMH with -ΔV Termination
Sensitivity of 2mV (typ)
Monitors Voltage, Temperature and Time for
Safety and Secondary Termination
