1A Li-Ion charger with USB interface
The MAX1874ETE+ is a single-cell lithium-ion battery charger IC from Analog Devices, delivering up to 1A charge current to a 4.2V battery pack. Its USB interface means the charge current can be drawn directly from a USB port without needing an external wall adapter — the IC handles the current-limiting and thermal regulation internally for a standard 5V USB bus.
Active production and compliance
RoHS3 compliant per the manufacturer's declaration, which covers the EU Restriction of Hazardous Substances directive for lead-free soldering processes. No official second-source or pin-compatible alternative is listed in the manufacturer's cross-reference data — the BOM position is single-sourced to this order code.
