<html><body><h2>Introduction</h2><p>The STC3115IJT is a battery management Power Management Integrated Circuit (PMIC) from STMicroelectronics. It is used to monitor, control and protect single-cell Li-ion batteries used in portable consumer applications. This includes portable media players, gaming consoles, smart phones, tablet PCs and digital cameras where increasingly long run times are required. It is designed to work with a wide variety of battery chemistries and substrates. By incorporating end-of-charge (EOC) and end-of-discharge (EOD) detections, the STC3115IJT can extend battery life and manage the use of energy more efficiently.</p><h2>Application Field</h2><p>The STC3115IJT provides advanced features to maximize the performance and runtime of Li-ion batteries in portable consumer applications. It can detect EOC and EOD conditions by monitoring battery cell voltages, current and temperature. It also implements a safe isothermal charge algorithm to regulate charge current as the charging voltage approaches target levels. Additionally, the STC3115IJT combines cell voltage, current and temperature inputs to accurately gauge the charge or discharge state of a battery. This enables the STC3115IJT to accurately report battery levels and to provide accurate estimates of remaining charge/time. The STC3115IJT is fully integrated and requires few external components. It is available in a 6-pad UDFN package and operates over an extended temperature range of -40°C to +85°C.</p><h2>Working principle</h2><p>The STC3115IJT is an advanced, feature-rich battery management IC. It provides a host of features to monitor and protect Li-ion batteries. At its core is an integrated microcontroller that samples battery cell voltages, currents and temperatures and calculates the charge and discharge states of the battery. The STC3115IJT also implements safety features to protect the battery and the system from adverse conditions such as over charging, over discharging, thermal runaway and short-circuiting. The STC3115IJT also implements a “safe isothermal” charge algorithm that regulates charge current and voltage as the battery approaches its full capacity. The STC3115IJT also has a built-in temperature monitor that can provide system-level temperature protection and extend battery life. Additionally, the STC3115IJT provides a “Fuel Gauge” that reports the exact state of charge (SOC) of the battery, provides estimates of remaining charge/time and reports the “Total Capacity” and “Minimum Remaining Capacity” of the battery.</p><h2>Conclusion</h2><p>The STC3115IJT is an advanced, feature-rich PMIC for single-cell Li-ion batteries used in portable consumer applications. It provides optimized charging for maximum runtime and battery life. It implements a safe isothermal charge algorithm to regulate charge current and voltage as the battery approaches its full capacity. It also provides extensive battery protection, system-level temperature protection and a fuel gauge that provides accurate estimates of remaining charge/time. The STC3115IJT is fully integrated and requires few external components, and is available in a 6-pad UDFN package and operates over an extended temperature range of -40°C to +85°C.</p></body></html>
