MAX2003 - Maxim

MAX2003 NiCd/NiMH Battery Fast-Charge Controllers

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.
