The S-8232AXFT-T2-G is a wide input voltage, low battery voltage drop Single Cell Li-Ion Battery Protection IC (Protection IC). This Protection IC can be used for many different applications, including automotive, portable electronics and industrial products. It is designed to protect the Li-Ion battery from over-voltage, over-current, and over-temperature conditions, as well as from reversed connections, discharge over-current and short-circuits. In addition, it can provide battery charge over-voltage protection, as well as a cell balancing feature for multiple battery cell applications. The S-8232AXFT-T2-G can be used for Lithium-Ion, Li-Po and LiFePO4 battery packs.

The design of the S-8232AXFT-T2-G IC is based on an integrated circuit process that features high-performance MOSFETs, analog circuitry and an accurate RTC (Real Time Clock). All components of the chip are integrated in a single package. This design allows the S-8232AXFT-T2-G to provide maximum current protection, while optimizing its overall size.

The S-8232AXFT-T2-G incorporates the following features and functions:

• Wide input voltage range: 4.5V to 28V
• Low battery voltage drop: 6 mV typical
• Battery charge protection: controllable voltage-up and voltage-down
• Over-voltage protection: adjustable trip point up to 4.6V
• Over-current protection: independent adjustable for charging, discharging and load currents
• Over-temperature protection: adjustable trip point
• Reversed connections protection: active low ‘’Detect’’ output pin
• Discharge over-current protection: adjustable trip point
• Short-circuit protection: adjustable trip point
• Cell balancing: drop in cell voltage or set a current limit
• Hysteresis: adjustable to control the frequency of balance cycles

The S-8232AXFT-T2-G is an ideal solution for battery management applications requiring high-performance, reliable protection and advanced cell balancing. It simplifies the design process by combining all the necessary protection, balancing and monitoring functions into a single package. The advanced balancing algorithm of the S-8232AXFT-T2-G ensures that all the cells in the battery are balanced accurately, quickly and safely.

The Working Principle of the S-8232AXFT-T2-G is based on monitoring the voltage of all the cells in the battery. The IC continuously monitors the threshold voltage of each cell and automatically adjusts the balancing current so that the cell with the lowest voltage is reaching the nominal voltage first. Once all the cells in the battery have reached the same voltage, the IC will turn off the balancing current and provide protection against over-voltage and short-circuits.

The S-8232AXFT-T2-G IC is ideal for automotive, portable and industrial applications. It provides high-performance protection with minimum current loss, which increases the operating time of the battery. This makes the protection IC an indispensable part of modern battery management systems, providing maximum reliability.
