MP26121DQ - 1A Li + Linear Battery Charger

Download the MP26121DQ datasheet PDF. This datasheet also covers the MP26121 variant, as both devices belong to the same 1a li + linear battery charger family and are provided as variant models within a single manufacturer datasheet.

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.

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 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.
