ISL6292-2CR4

The ISL6292-2CR4 is a highly integrated, high-efficiency dual-channel stand-alone Li-Ion and Li-polymer battery charging IC. It provides two charge channels to simultaneously charge two separate battery packs and support two different output voltage levels. This IC also supports fast charge (TC-FC) and also supports charge-top balancing and temperature sensing. In this article, we will explore the application field and working principle of the ISL6292-2CR4.

Applications

The ISL6292-2CR4 is suitable for use in applications such as mobile phones, digital cameras and PDAs, as well as automotive and industrial applications. This IC is optimized for charging Li-Ion and Li-polymer battery packs up to 8 cells in series, and also supports up to 8 cells in parallel. It offers adjustable charge current and charge voltage, as well as charge termination based on cell voltage, temperature and time.

The IC also provides a wide variety of safety and protection features. These include over voltage protection, under voltage protection, reverse battery protection, high temperature protection and short circuit protection. Additionally, the ISL6292-2CR4 supports pre-conditioning, fast charge and non-linear charging. This makes it suitable for use in applications that require maximum power efficiency and reliability.

Working Principle

The ISL6292-2CR4 utilizes a two-level charging system, whereby each battery pack is charged separately. The charging system has two operating stages, the constant current stage and the constant voltage stage. During the constant current stage, the charging current is adjusted based on the battery\'s total capacity and its state of charge. This stage aims to charge the battery up to approximately 80% capacity. In the constant voltage stage, the charging voltage is sustained until the charging current falls below a set threshold. This finalizes the charging process, leading to full capacity charging.

In order to ensure maximum safety and reliability, the ISL6292-2CR4 utilizes several safety and protection features. These include over voltage protection, under voltage protection, reverse battery protection and short circuit protection. Additionally, the IC offers pre-conditioning, fast charge and non-linear charging, allowing for a fast and efficient charging process.

In addition to the charging system, the ISL6292-2CR4 also provides several charging indicators. These indicate the charging status as well as the charge complete state. This allows the user to monitor the process and take any necessary action.

Conclusion

The ISL6292-2CR4 is a highly integrated, high-efficiency dual-channel stand-alone Li-Ion and Li-polymer battery charging IC that is suitable for use in mobile phones, digital cameras and PDAs, as well as automotive and industrial applications. It utilizes a two-level charging system and provides several safety and protection features. The ISL6292-2CR4 is an ideal choice for applications that require maximum power efficiency and reliability.
