The AP9211S-AD-HAC-7 is a multi-channel, battery management system that provides a cost-effective and reliable solution to monitor and protect battery cells in prismatic and cylindrical Li-ion and Li-polymer battery packs. It boasts a high accuracy analog front-end and multiple components that provide the highest level of performance and reliability.

AP9211S-AD-HAC-7 is an advanced battery management chip that can monitor and protect multiple battery cells in a single device. It features an I2C interface for easy integration into system designs. The chip uses an integrated switched capacitor precision analog front-end that can accurately measure cell voltage and current. It also features low power operation and flexible configuration options.

Application Field:

The AP9211S-AD-HAC-7 can be used in various battery-powered devices. It is especially useful for applications where batteries need to be monitored and balanced intelligently, such as in notebooks, two-way radios, cordless tools, and electric vehicles. Furthermore, the AP9211S-AD-HAC-7 can be used in a variety of battery pack configurations, providing a cost-effective and reliable solution.

Working Principle:

The AP9211S-AD-HAC-7 operates by measuring the voltage and current of different battery cells and adjusting the charging or discharging currents accordingly. The voltage and current of each cell is monitored simultaneously and the power is regulated after comparing the measurements to a predetermined set of values. When the current and voltage of a cell differ from the pre-programmed thresholds, the AP9211S-AD-HAC-7 will instruct the battery management system (BMS) to either increase or decrease the charging or discharging current to bring the cell back into balance.

The AP9211S-AD-HAC-7 also features a temperature sensor and a gas gauge to help optimize the performance and longevity of the battery. It can also monitor cell temperatures to help prevent overheating. It is capable of monitoring up to 12 cells, and it also has the ability to detect faults in the cells and isolate them to avoid a chain reaction. Additionally, the AP9211S-AD-HAC-7 is capable of providing fault feedback to a controller so that maintenance personnel can be alerted of a fault.

The AP9211S-AD-HAC-7 also features an automatic protection circuit to identify and protect against short-circuits and over-voltage or over-current conditions. Moreover, it offers a wide range of features, such as programmable parameters for voltage, current, and temperature thresholds, status flags indicating cell imbalance, and support for cell balancing. Additionally, it can also be used for monitoring the health of the battery, such as the state of charge, capacity, and health.

The AP9211S-AD-HAC-7 is a reliable and cost-effective solution for monitoring and protecting battery cells. It provides the highest level of performance and reliability, and is easy to integrate into system designs. With its wide range of features and its ability to monitor up to 12 cells, it is an ideal choice for battery-powered applications.
