Versatile NiMH chip charges 10 cells in series

Dallas – Dallas Semiconductor’s DS2715 battery-pack charge controller can be optimized for a variety of charging scenarios for either removable or embedded battery packs containing one to 10 nickel metal hydride (NiMH) cells in series. It can be configured as a switched DC charger, a linear current regulator, or a switchmode current source. Charge rates between 150 mA and 2 amps can be user-selected with an external sense resistor. Typical applications for the DS2715 include portable DVD players, portable television sets, hand-held gaming, hand-held POS terminals, and test equipment.
