Learn the goals of fuel gauging and the different ways in which it can be achieved. The advantages and disadvantages of different types of gauging are discussed as well as how to implement a fuel gauge.
Learn about Texas Instruments’ patented Impedance TrackTM technology and the advantages it offers. In addition it will outline the overall benefits of fuel gauging and the consequences of not implementing gauging correctly within your system.
This module covers the fundamental ideas behind circuit protection, including hotswap, current limiting, OVP, eFuse, etc. It highlights what circuit protection is designed to do, which types of circuits are normally protected, where it is used, and the basic parts of circuit protection.
This module covers circuit protection device features and options. Choices such as internal or external FET, fault response types, I2C or analog control, and ORing control are covered in this lecture. Questions that should be asked during a typical design are also addressed.
In this lecture we examine common design errors when working with protection circuits, specifically Safe Operating Areas of FETs being too small, issues with layout, and having inadequate transient protection.
In this lecture we address common test errors: current probes and the related problems taking precise DC measurements, electronic loads, transients from long supply leads, and setting supply currents too low.
