DS2715
NiMH Battery Pack Charge Controller

DESCRIPTION
The DS2715 is well suited for cost-sensitive charger
PIN CONFIGURATION
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.
