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.","metaTitle":"MAX1870AETJ+T Analog Devices Multi-Chem Battery Charger, 4A","metaDescription":"MAX1870AETJ+T Analog Devices multi-chemistry battery charger IC, 2-4 cells, 4A max charge current, 28V input, -40 to 85°C, 32-TQFN.
