    1. TI Fuel Gauge Application Guide

      Lithium batteries are increasingly used, and people are paying more and more attention to and demanding lithium battery safety and battery life user experience. The demand and application of gas gauges (gas gauges or fuel gauges or gauges) are also increasing. TI (Texas Instruments) has been continuously developing battery management solutions since the 1990s. As of today, there are 477 battery management ICs on sale on TI\'s official website, including 115 fuel gauge ICs. The product line covers a wide range of applications, supporting single-string to multi-string battery cells, supporting a variety of battery chemistry types such as Li-ion, LiFePO4, etc., supporting mobile phones, tablets, laptops, TWS headphones, power tools, vacuum cleaners, electric bicycles, drones, energy storage, and other market applications. There are discrete fuel gauges and fuel gauges with integrated protection, and patented Impedance TrackTM impedance tracking, CEDV and other algorithms. Part 1 Introduction to the basics of fuel gauges. Introduce what a fuel gauge is, what a fuel gauge can do, how a fuel gauge measures, and how to select a fuel gauge. Part 2: Fuel meter development and mass production process. It is divided into 6 chapters, introducing the impedance tracking fuel meter development process, chemical ID acquisition method, Golden Learning method, mass production file introduction, mass production process, CEDV fuel meter development and mass production process, and common fuel meter tools. Part 3: Fuel meter calculation method. It is divided into 5 chapters, introducing the principle of impedance tracking fuel meter calculation method, the principle of CEDV fuel meter calculation method, how to evaluate the accuracy of fuel meter, introducing the fuel meter RSOC update mechanism and the analysis of jump scenarios that users often care about, introducing the fuel meter FCC update mechanism and the analysis of FCC small scenarios that users often care about. Part 4: Fuel meter circuit design. It is divided into 5 chapters, introducing the fuel meter peripheral circuit design, PCB Layout design, battery balancing algorithm and circuit implementation, the impact of failure of fuel meter peripheral components, and introducing the common false current cause analysis and solutions in battery circuits. Part 5: Fuel meter access and communication. It is divided into 4 chapters, introducing the fuel gauge security mode and access control, fuel gauge communication and parameter reading and writing methods, fuel gauge communication abnormality problem analysis method, fuel gauge Checksum/Signature, etc. Part 6 Typical Application Design Points. It is divided into 5 chapters, introducing the design points of fuel gauges in several typical applications such as smart phones, fast charging mobile phones, small capacity consumer battery applications, large capacity and high rate industrial battery applications, etc.

    2. Xidian-Printed Circuit Board (PCB) Design Guide_1-99

      ? Why is my circuit simulation OK, but the actual accuracy is very poor? ? Why is the ADC data jump (noise) so strong? ? Why does my amplifier circuit self-excite or howl? ? Why do digital circuits always have inexplicable logical errors? ? Why does my microcontroller control board always freeze and run away? ? How thick should the wire be to drive a 1A load? ? What is the appropriate insulation spacing for a 220V power inlet? ? Why do the solder joints of the power tube always melt?
