♦ Stand-Alone NiCd or NiMH Fast Chargers

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.

♦ New Pulsed Trickle-Charge Mode (MAX2003A only)

♦ Provide Switch-Mode, Gated, or Linear Control

Regulation

♦ Small, Narrow SO Package Available

♦ On-Chip Fast-Charge Termination Methods:

• Temperature Slope

• Negative Delta Voltage

• Maximum Temperature

• Maximum Voltage

• Maximum Time

♦ Automatically Switch from Fast-Charge to

On-chip algorithms determine charge termination, so the

MAX2003/MAX2003A c a n b e us e d a s s ta nd -a lone

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

a re within s a fe limits . By s e le c ting the a p p rop ria te

charge-termination method, a single circuit can be built

with the MAX2003/MAX2003A to fast-charge both NiMH

and NiCd batteries.

Trickle-Charge or Top-Off Charge

♦ Optional Discharge-Before-Charge

♦ Directly Drive Status LEDs

♦ Optional Top-Off Charge

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.
