Battery charging parameters for design fit
The MAX1870AETJ+ handles 2 to 4 series cells with a programmable constant-current charge profile, delivering up to 4 A max charge current. Maximum battery pack voltage is 17.6 V, and the IC accepts a supply rail up to 28 V — the input must be regulated below that ceiling or protected against transients that exceed it. Chemistry flexibility is built in: the Multi-Chemistry designation means the charge algorithm can be configured for Li-ion, Li-Poly, NiMH, or NiCd packs without a hardware swap.
Delivered in tube packaging, not tape-and-reel — factor this into the pick-and-place feeder setup if the line expects reel-fed parts.
ROHS3 compliant, which covers the ten restricted substances plus four phthalates — no additional exemption declarations needed for EU-market builds.
