Based on its powerful driving capability, S-8261AALMD-G2LT2G is widely applied in mobile phones, mobile phones accessories, digital cameras, vehicle-mounted systems, etc. Moreover, with various features of overvoltage protection, overcurrent protection and pre-charging, S-8261AALMD-G2LT2G can improve the reliability of battery-powered system.

Working principle of S-8261AALMD-G2LT2G

In the rectifier circuit, the S-8261AALMD-G2LT2G receives the drive voltage and battery input current, converts them into suitable voltage levels, and then feeds them into the PWM comparator inside. The PWM comparator compares the input signals and adjusts the output voltage of the rectifier to the required voltage level according to certain algorithms. Meanwhile, the frequency modulation circuit connected to the PWM comparator will adjust the frequency of the output voltage according to the adjustment of the comparator, in order to maintain a stable output power. Furthermore, S-8261AALMD-G2LT2G is equipped with an overvoltage protection circuit, which can detect the danger of overvoltage and adjust the output voltage or current immediately. At the same time, the overcurrent protection circuit will be activated once the charging current exceeds the design value, and then it will start the overcurrent protection mode. Therefore, S-8261AALMD-G2LT2G has the ability to protect the battery in its application field.

Conclusion

To sum up, S-8261AALMD-G2LT2G is an IC designed for the efficient management of power in electronic systems. It is widely used in the protection of batteries used in hand-held and portable electronic products, such as mobile phones, mobile phones accessories and digital cameras. Meanwhile, its working principle is based on the rectifier circuit, the PWM comparator, the frequency modulation circuit and the overvoltage and overcurrent protection circuits, which can improve the reliability of battery-powered system.
