MP26121 Datasheet | Monolithic Power Systems

DESCRIPTION The MP26121 is a linear, high-performance single cell Li-Ion/Li-Polymer battery charger. By integrating high voltage input protection into the charger IC, the MP26121 can tolerate an input surge up to +28V. The device features constant current (CC) and constant voltage (CV) charging modes with programmable charge currents (200m A to 1A), current blocking, and trickle charge. The device also provides fault and charge status indications to the system. For guaranteed safe operation, the MP26121 reduces charge current when the device reaches high temperature (due to limited PCB space). Other safety features include battery temperature monitoring and programmable timer to plete the charging cycle. The MP26121 is available in a QFN-10 (3mmx3mm) package.
