In designing personal electronics, industrial or medical applications, engineers must address some of the same challenges: how to increase performance, add features and shrink form factors. Along with these considerations, they must carefully monitor temperature to ensure safety and protect systems and consumers from harm. In this first chapter of Temperature Sensing Precision Labs, we teach the fundamentals of temperature sensing - application use-cases for temperature sensors, the various types of temperature sensors and the trade-off each sensor type presents.
These introduction videos give the background on magnetic concepts and Hall Effect ICs for engineers of all experience levels. The second video introduces the magnetic field calculator Texas Instruments created to aid in design challenges.
Understanding the key specifications of Hall sensors will aid in ensuring the proper device is selected for a given application. The series of videos in this section will give a thorough explanation of the tradeoffs in bandwidth versus power, the importance of the operate and release point in Hall Effect switches and latches and the key parameters for linear Hall Effect sensors.
There are a variety of applications for Hall Effect sensors, each with its own unique system requirement. The series of videos in this section will walk through some of the top Hall applications such as rotary encoding and proximity sensing.
When designing Hall applications, understanding the behavior of magnetic fields is crucial. The series of videos in this section will discuss how magnetic fields vary with temperature and axis of rotation.
For anti-tampering, it is common to try to detect the presence of a strong magnet. In this section, we will cover the use of hall sensors for low-power detection of strong magnetic fields in three dimensions. Details on our magnetic tamper detection reference design, TIDA-00839, will be provided as well as some of the design considerations that were kept in mind when creating this reference design.
In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.
