Battery Management ICs
A Battery Management IC is a specialized microcontroller that monitors and manages the charging and discharging of a lithium-ion or other type of battery. These ICs are essential for ensuring the safe and efficient operation of batteries in a wide range of applications, including portable electronics, electric vehicles, and renewable energy systems. One of the key functions of a Battery Management IC is to optimize the charging and discharging of a battery by controlling the flow of current. This can help to extend the life of the battery and improve its overall performance. In addition to controlling the charging and discharging of a battery, a Battery Management IC can also perform other functions such as monitoring the temperature and voltage of the battery, protecting the battery from overcharge and overdischarge, and providing diagnostic information about the battery's health. Flux.ai has the world's largest community-driven public library of Battery Management ICs, with footprints, symbols, datasheets, and simulation models available for use. Whether you are a designer, engineer, or researcher, the Flux.ai library is an invaluable resource for finding the right Battery Management IC for your project.
GLF1100-T1G7
Power Switch/Driver 1:1 P-Channel 2A SOT-23-5 The GLF1100 is an ultra-efficiency, 2 A rated, Load Switch with integrated slew rate control. The best in class efficiency makes it an ideal chose for use in IoT, mobile, and wearable electronics. The GLF1100 features ultra-efficient IQSmartTM technology that supports the lowest quiescent current (IQ) and shutdown current (ISD) in the industry. Low IQ and ISD solutions help designers to reduce parasitic leakage current, improve system efficiency, and increase battery lifetime. The GLF1100 integrated slew rate control can also enhance system reliability by mitigating bus voltage swings during switching events. Where uncontrolled switches can generate high inrush currents that result in voltage droop and/or bus reset events, the GLF slew rate control specifically limits inrush currents during turn-on to minimize voltage droop. GLF1100 Load Switch devices support an industry leading wide input voltage range and helps to improve operating life and system robustness. Furthermore, one device can be used in multiple voltage rail applications which helps to simplify inventory management and reduce operating cost.

Battery Power Management IC Multi-Chemistry 14-TSSOP The bq34210-Q1 1-Series Cell System-Side CEDV Fuel Gauge provides fuel gauging and End-of-Service (EOS) Determination for 1-series cell batteries in applications that encounter infrequent discharge, such as eCall systems and uninterruptible power supplies (UPS) for backup during power failures, where batteries may stay connected to a charging power source most of their lifetime until needed. The bq34210-Q1 fuel gauge supports multiple battery chemistries, including Li-Ion, LiFePO4, and NiMH. The gas gauging function uses voltage, current, and temperature data along with Compensated End-ofDischarge (CEDV) technology to provide State-ofCharge (SOC) and State-of-Health (SOH) data. The device's EOS Determination function alerts when battery capability has degraded and is approaching the end of its usable service.
