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.
