The S-8241ABAMC-GBAT2G family is a range of highly efficient battery management and control integrated circuits for providing precise voltage, current, temperature and state of charge monitoring for different types of rechargeable batteries. It is a complete solution for portable and stationary applications that require precise and accurate measurements, precise control and improved battery cycling capability. The S-8241ABAMC-GBAT2G is a low-voltage, low-power solution based on the advanced battery management and control integrated circuitry.

The S-8241ABAMC-GBAT2G contains all the necessary hardware blocks including a 16-bit microcontroller, 2 voltage converters, a pulsewidth modulator, 7 serial digital-to-analog converters, 6 analog-to-digital converters, and a real-time clock. The digital-to-analog and analog-to-digital converters provide the accuracy and precision necessary for proper battery conditioning. Additionally, the pulsewidth modulator is used to generate switching pulsewidth modulated waveforms for precise control of the charge and discharge. Finally, the real-time clock provides timers for accurate timekeeping during operation and for time critical tasks such as calibration, wear leveling and cell balancing.

The S-8241ABAMC-GBAT2G uses a sequenced loop, or a command-driven approach, to managing battery operations and communication. The Sequenced Loop, or SL, allows the operator to use an intuitive command set to control, monitor and configure a variety of parameters such as charge and discharge current, cell voltage, temperature limit and cell balancing, as well as peripheral settings. The SL prevents the execution of critical commands in an improper sequence, allowing additional safety to be built into the design.

The S-8241ABAMC-GBAT2G can provide additional functionality through protection systems, such as over-voltage, overcurrent, undervoltage and overtemperature protection, allowing the system to be designed with lower over-design margins. Fault tolerance functions can also be enabled, such as opening the relay after detecting a fault, automatically going into a safe state, and controlling the charging to avoid long-term damage if overcurrent is detected.

The S-8241ABAMC-GBAT2G also supports efficient multi-cell charging and monitoring. This allows charging and monitoring of multiple packs in parallel, thereby reducing system costs. Furthermore, the S-8241ABAMC-GBAT2G is capable of performing cell-balancing operations using pulse-width modulated current pulses to charge or discharge individual cells, yielding improved life and performance of the battery.

Overall, the S-8241ABAMC-GBAT2G provides a comprehensive solution for battery management and control in a compact package. It allows for efficient multi-cell charging and monitoring, precise voltage and current monitoring, and advanced protection features. With its intuitive sequential loop structure and core features, it is ideal for a variety of purposes in both stationary and portable battery applications.
