S-8254AAIFT-TB-G

S-8254AAIFT-TB-G is a Li-ion/Polymer battery management IC designed to support single cells up to 4 cells in series. It provides improved safety and system performance in lithium-based battery packs. This IC can be used in a wide range of portable devices, such as car navigation systems, digital still cameras, and portable audio players.

The S-8254AAIFT-TB-G IC integrates a controller IC, two MOSFETs, and a built-in current sensing circuit. This allows it to effectively protect the battery from overcharging, over-discharging, and over-current challenges. It also supports advanced measurement functions, such as LED control, error detections, and thermistor detection.

The S-8254AAIFT-TB-G provides a wide range of features, including maximum charge and discharge current, maximum charge voltage, operational temperature range, and an auto-off timer. It also supports auto-resume, allowing it to quickly resume operation after an over-discharge event. Additionally, the IC integrates a unique low-voltage drop protection circuit, that is designed to minimize the total system power consumption in most applications.

The working principle of the S-8254AAIFT-TB-G IC is simple. It provides the necessary power to the battery when charging and limits the amount of current that is allowed to flow through the battery. The IC also monitors the voltage level of the battery and shuts off the power when the battery is fully charged. When discharging, the IC regulates the amount of current that is allowed to flow, preventing the battery from over-discharging. Furthermore, the IC also monitors the temperature of the battery, shutting off the power when the temperature reaches a certain value, to increase battery safety and lifetime.

In summary, the S-8254AAIFT-TB-G is a highly integrated Li-ion / Polymer battery management IC designed to ensure maximum safety and system performance. It effectively balances the correct input and output of power, optimizing the charge and discharge of the Li-ion / Polymer battery. Furthermore, it also monitors the battery temperature and current level, shutting off power when necessary, to prevent overcharging, over-discharging, and over-current conditions. With these features, the S-8254AAIFT-TB-G is an ideal choice for high-performance, cost-effective, battery management solutions.
