ISL6292-2CR3Z

ISL6292-2CR3Z is a high performance, integrated single-cell Li-Ion/Li-Polymer charger integrated circuit. It is specially designed for the charging of a single cell Li-Ion battery. This chip supports two types of charging methods, Constant Current/Constant Voltage(CC/CV) charging mode and the Low Drop-Out(LDO) charging mode.

ISL6292-2CR3Z belongs to the Power Management Integrated Circuit (PMIC) – Battery Chargers category and it is an ideal power solution for moderate to high power applications such as notebook computers, tablet PCs, digital cameras, and other high-drain devices.

The application field of ISL6292-2CR3Z is relatively wide, it is suitable for the charging of multiple types of Li-Ion/Li-Polymer batteries, such as Li-Ion battery cells with 3.2V, Li-Ion battery cells with 3.7V and Li-Ion battery cells with 4.2V. With the precise voltage and current sensing, the ISL6292-2CR3Z can accurately track both the peak current and the end voltage through the settings of the CV and PEAK registers.

ISL6292-2CR3Z works according to the principle of constant current/constant voltage (CC/CV) charging method. Under the CC/CV mode, the circuit charges the battery with a constant current, and then the current gradually decreases until it reaches the battery end voltage. When the voltage reaches the value of the CV register, the battery enters the CV mode and the charging current drops to a preset value. The battery is then fully charged.

ISL6292-2CR3Z is also equipped with other features such as overcharge prevention and undervoltage protection. The charger also includes other protections, such as short circuit protection, reverse current protection, cell overvoltage and overtemperature protection, to ensure the safety of the device and prevent any damage or malfunctions.

In conclusion, ISL6292-2CR3Z is a high performance, integrated single-cell Li-Ion/Li-Polymer charger integrated circuit. Its application fields are relatively wide and it suits the charging of a wide range of Li-Ion/Li-Polymer batteries. The working principle of ISL6292-2CR3Z is according to the CC/CV charging method and it also includes other protections such as overcharge prevention and undervoltage protection.
