DS2714  
Quad Loose Cell NiMH Charger  
www.maxim-ic.com  
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.  
Cꢀ Charges 1 to 4 NiMH Cells  
Cꢀ Detects and Avoids Charging Alkaline Cells  
Cꢀ Pre-Charges Deeply Depleted Cells  
Cꢀ Fast Charges NiMH with -V Termination  
Sensitivity of 2mV (typ)  
Cꢀ Monitors Voltage, Temperature and Time for  
Safety and Secondary Termination  
Cꢀ Works with Regulated Charge Current Source  
Cꢀ Drives PNP Type Pass Element  
APPLICATIONS  
Desktop/Standalone Chargers (AAA/AA)  
Digital Still Cameras  
Music Players  
Cꢀ Compatible with Integrated Primary-Side PWM  
Controllers
