The MAX8804W/MAX8804Y/MAX8804Z are intelligent, dual-input, stand-alone, constant-current, constant-voltage (CCCV), thermally regulated linear chargers designed for a single-cell lithium-ion (Li+) battery. They integrate the current-sense circuit, MOS pass element, thermal-regulation circuitry, and overvoltage protection (OVP), and eliminate the reverse-blocking Schottky diode to create a simple and small charging solution for handheld equipment.
The MAX8804W, MAX8804Y and MAX8804Z are high‑voltage, dual‑input linear charger ICs designed for single‑cell Li+ batteries. They integrate current‑sense circuitry, MOS pass element, thermal regulation and over‑voltage protection, eliminating the need for external FETs or blocking diodes. The devices automatically select between a USB or AC adapter source and provide programmable fast‑charge currents.
The datasheet details absolute maximum ratings, electrical characteristics, typical operating curves, pin descriptions, and package dimensions for the 2 mm × 3 mm TDFN package. It also includes ordering information and revision history for reference.
