The MAX2003/MAX2003A are fast-charge battery charg-

ers (with conditioning) for NiCd (nickel cadmium) or

NiMH (nickel-metal hydride) rechargeable batteries. The

MAX2003A has the same features as the MAX2003 with

an additional pulsed trickle-charge mode to prevent den-

drite formation in NiMH batteries. Each can be config-

ured as a switch-mode current regulator or as a gating

controller for an external current source. Switch-mode

current regulation provides efficient energy transfer,

reducing power dissipation and the associated heating.

Gating control of an external current source requires

minimal components, saving space and cost.

On-chip algorithms determine charge termination, so the

MAX2003/MAX2003A can be used as stand-alone

chargers. Fast-charge termination is accomplished by

five methods: temperature slope, negative voltage

change, maximum temperature, maximum time, and

maximum voltage. As a safety feature, the start of fast-

charge is inhibited until battery voltage and temperature

are within safe limits. By selecting the appropriate

charge-termination method, a single circuit can be built

with the MAX2003/MAX2003A to fast-charge both NiMH

and NiCd batteries.

The MAX2003/MAX2003A provide a switch-activated

discharge-before-charge option that allows for battery

conditioning and more accurate capacity measure-

ment. Other features include optional top-off charging

and direct drivers for LED status lights.

The MAX2003, in DIP and wide SO packages, is a direct

plug-in replacement for the bq2003. The MAX2003/

MAX2003A also come in a space-saving narrow SO

package. The MAX2003A evaluation kit (MAX2003A

EVKIT-SO) is available to assist in designs.
