MAXIM INTEGRATED / ANALOG DEVICES MAX1874ETE Li-ion Battery Charger
The MAX1874ETE+ is a dual-input, USB and AC adapter, 1-cell Lithium-ion battery charger packaged in a 16-pin TQFN package. It features battery-to-input power switching, allowing the system to be powered directly from the power source instead of the battery. The device includes thermal regulation, input overvoltage protection, and soft-start functionality. It supports charging from USB or an AC adapter with automatic switchover to the AC source as needed. The charger provides active-low status outputs for charging (CHG), power-good signals for DC (DCOK), USB (UOK), and power-on (PON), which can control external MOSFETs for power management and overvoltage protection. Additional features include input protection up to 18V, linear charge regulation at 1A, and operation over a temperature range from -40°C to 85°C. On-chip thermal limiting ensures safety during operation. Suitable applications include power management systems and portable devices.
