DS2715  
NiMH Battery Pack Charge Controller  
www.maxim-ic.com  
DESCRIPTION  
PIN CONFIGURATION  
The DS2715 is well suited for cost-sensitive charger  
applications where the battery pack is either internal  
or external to the application. It has been optimized for  
safe and reliable charging of 1 to 10 NiMH cells in  
series. The internal gain block can be selected as  
either a comparator or transconductance amplifier for  
charge current regulation. This makes the DS2715  
configurable as a switched DC charger, a linear  
current regulator, or a switchmode current source.  
The DS2715 pre-conditions severely depleted cells  
before entering full charge mode. It terminates full  
charge using the dT/dt technique, which requires an  
external sensing thermistor. Over-temperature, under-  
temperature, and over-voltage detection prevents  
charging under unsafe conditions. A user selectable  
charge timer allows charge rates from 0.167C to 2C.  
FAST-CHARGE, TOPOFF and DONE modes are  
included for highly reliable, safe charging of NiMH  
cells. Discharge mode allows the DS2715 to enter a  
low power sleep state while the cell pack is being  
discharged.
