Product details

Multi-chemistry charger in a 5×5 mm TQFN

The MAX1870AETJ+T is a multi-chemistry battery charger IC from Analog Devices, supporting 2 to 4 series cells with a programmable constant-current charge up to 4 A.

Charge current and pack voltage limits

The 4 A maximum charge current supports fast charging of multi-cell Li-ion, Li-Poly, or NiMH packs — the actual charge rate is set by the external sense resistor and the programming pin, not fixed internally. Battery pack voltage tops out at 17.6 V, which corresponds to a 4-series Li-ion stack at 4.2 V per cell or a 4-series LiFePO4 stack at 3.65 V per cell — the chemistry selection is external.
