MP26121DQ Datasheet 1a Li + Linear Battery Charger

Manufacturer: Monolithic Power Systems

Overview: MP26121 28V, 1A Li + Linear Battery Charger with 10% Battery-Full Threshold and Flexible NTC.

This datasheet includes multiple variants, all published together in a single manufacturer document.

Datasheet Details

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

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 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 complete the charging cycle. The MP26121 is availabl.
