_______________General Desc ription
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.
