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.","metaTitle":"Analog Devices MAX1870AETJ+ Battery Charger IC, 4A, 32-TQFN","metaDescription":"MAX1870AETJ+ multi-chemistry battery charger IC from Analog Devices.
