MP2631DQ-LF-Z is a multifunctional battery charger that is used in a variety of applications. It is part of Monolithic Power Systems\' Power Management IC (PMIC) family and is designed to provide a high level of performance, safety and reliability. The MP2631DQ-LF-Z provides highly efficient charging capabilities and also offers features such as over-current and battery temperature protection, reverse conduction protection, short-circuit protection, and soft start.

The MP2631DQ-LF-Z is a low-dropout (LDO) linear battery charger with a maximum operating current of 1.8A. It is primarily designed to charge Li-Ion and Li-Polymer batteries. It is also capable of charging MOSFET battery types such as Ni-MH, Ni-Cd, and Alkaline. Furthermore, the charger is able to provide accurate constant current-constant voltage (CC/CV) charging.

Working Principle

The MP2631DQ-LF-Z consists of a linear voltage regulator, a FET switch, and a comparator. When a battery is connected and charged, an input voltage is applied to the FET switch. The switch allows the battery to be charged up to the specified voltage and current levels. As the battery is charged, the FET switch closes, thus allowing current to flow from the voltage regulator to the battery.

The MP2631DQ-LF-Z also contains a temperature monitor which is used to determine the operating temperature of the battery. The temperature monitor will shut off the charge current if the temperature rises above the specified safe charging level. Furthermore, the comparator will protect the battery from overcharging if the battery voltage exceeds the specified charge level.

The MP2631DQ-LF-Z is also capable of providing accurate constant current-constant voltage (CC/CV) charging. This ensures a consistent supply of power and ensures that the battery will reach its maximum charge level and remain safe during the charging process. The device offers a wide range of charging settings, including the output voltage and current, the charge current limit, and the charge timeout.
