MP2617GL-Z

PMIC - Battery Chargers

Power management integrated circuits (PMICs) are chips that are used to manage power in systems. Battery chargers are one of the applications of PMICs, and the MP2617GL-Z is an example of this type of device. It is an integrated single-cell Li-Ion and Li-Polymer battery charger. The device is designed to charge Li-Ion and Li-Polymer batteries from 0~4.275V with a programmable charge current up to 1A. It can be combined with other analog and digital functions for further system design possibilities.

Purpose and Role of the MP2617GL-Z

The main purpose of the MP2617GL-Z is to charge a Li-Ion or Li-Polymer battery in a portable device. It is frequently used in cell phones, digital cameras, PDA’s, MP3 players, and other portable electronics. It is also suitable for use in battery packs on electric bikes, power supplies, and fuel cells.

Working Principle of the MP2617GL-Z

The internal workings of the MP2617GL-Z follow the charge cycle described for Li-Ion and Li-Polymer batteries. In this process, the charging voltage is maintained at a highly controlled level. During the charge cycle, the voltage is kept within a specified range known as constant voltage. When this voltage is reached, the current is gradually reduced, until it reaches a level known as constant current. This stage is repeated until the battery reaches its full charge.

The MP2617GL-Z has several important features that make it an ideal choice for portable devices. It is designed to reduce the number of component count and increase system systematic efficiency. It is also designed to protect against overvoltage, over temperature, and overcharge conditions. Additionally, it can be used in conjunction with existing system components, including a microcontroller, in order to ensure maximum safety and compatibility.

Conclusion

The MP2617GL-Z is a highly capable and reliable power management integrated circuit. It is suitable for charging Li-Ion and Li-Polymer batteries in a wide range of portable devices, and is designed to increase efficiency and reduce component count. Its ability to protect against overvoltage, over temperature, and overcharge conditions makes it a popular choice for many consumer electronics and smaller power systems.
