Application Field and Working Principle of AP9101CK-AGTRG1

Battery Management

The AP9101CK-AGTRG1 is a two-cell battery management solution that offers high-performance, low-noise, and low-cost integrations of the battery power management system, with several integrated hardware and software features to handle cell balancing, voltage supervision, and cell state observation. The device is designed to monitor two battery cells in parallel configurations, and is optimized to meet the needs of 1S2P and 1S3P systems.

The device has an internal voltage detector, which can detect the voltage of the two battery cells in parallel connection in real time and compare them to the preset threshold. When the voltage of one battery cell is lower than the preset threshold, the device can start charging the lower battery automatically. The AP9101CK-AGTRG1 also provides cell imbalance capability, which can reduce the charging current of the higher battery to equalize the state of charge of the two cells in the pack.

Power Supply

The AP9101CK-AGTRG1 integrates advanced charging algorithms, external power monitor circuit and full-protection functions, and provides a fast, safe and efficient charging solution. With its fast-charging feature, the charge current can be set as high as 3A to ensure fast charging, while also ensuring high reliability and a full-protection of the lithium battery.

In addition, the device also provides an external power monitor circuit, which can monitor the input voltage, input current and output current in real-time. This feature can help to prevent over-voltage, over-current and over-temperature conditions from damaging the battery. When the detected voltage or current exceeds the preset range, the device can provide the necessary protection for the battery.

Conclusion

The AP9101CK-AGTRG1 device is an ideal two-cell Battery Management and power supply solution for 1S2P and 1S3P applications. It integrates voltage detector, cell balance, voltage supervision, cell state observation, charging algorithms, external power monitor circuit and a full-protection function. All these features ensure a maximum system integration, excellent performance and high reliability.
