Single-cell Li-Ion charger with 2.5 A ceiling
Charge current programming and protection
Charge current is constant and programmable, so the BOM resistor or firmware sets the rate per the battery capacity. The 2.5 A ceiling supports fast charging for cells rated at 2500 mAh or higher, but the thermal budget in the 24-VFQFN package with exposed pad must be checked against the PCB copper area. On-chip fault protection covers over-temperature and short-circuit conditions, which is the safety layer that prevents thermal runaway during a fault event.
USB input and temperature range
The USB interface means the charger accepts 5 V from a standard USB port or adapter, with a maximum supply voltage of 10 V.
