MP26053

The MP26053 is a linear, high performance single cell Li-Ion/Li-Polymer battery charger. By integrating high voltage input protection into the charger IC, the MP26053 can tolerate an input surge up to +28V. In addition, the MP26053 features an internally programmed precision battery full-threshold of 10% of ICHG. The device features constant current (CC) and constant voltage (CV) charging modes with programmable charge currents (200mA to 1A), current blocking, and trickle charge. The device also provides fault and charge status indications to the system. For guaranteed safe operation, the MP26053 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 complete the charging cycle. The MP26053 is available in 10-pin 3mm x 3mm QFN packages.
