Overview
MAX2003/MAX2003A 19-0371; Rev 4; 5/97 EVFAOLLULAOTWIOSNDKAITTAMSAHNEUEATL NiCd/NiMH Battery Fast-Charge Controllers General Description The MAX2003/MAX2003A are fast-charge battery chargers (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 dendrite formation in NiMH batteries.
Each can be configured 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 tempera...
