Part 3: Li-ion battery discharge curves and estimate battery operating time gains with buck-boost

In this section, you will become familiar with lithium ion battery discharge curves and learn in which use cases a buck-boost converter will significantly increase battery operating time.

Understanding MOSFET datasheets

When it comes to MOSFET datasheets, you have to know what you’re looking for. While certain parameters are obvious and explicit (BVDSS, RDS(ON), gate charge), others can be ambiguous at best (ID, SOA curves), while others can be downright useless at times (see: switching times).

Selecting a MOSFET

In complicated power designs, metal-oxide semiconductor field-effect transistor (MOSFET) selection has a tendency to be somewhat of an afterthought. While it’s just a three-pin device, appearances can be deceiving and trying to select the correct MOSFET or “FET” can be a task more complicated than you might think. In this 7-part blog series, we analyze a variety of typical FET applications, from power supply to motor control, and address the various concerns and trade-offs that dictate the FET selection process.

Detecting magnetic tampering using hall-effect sensors

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.  

Hardening a meter against magnetic tamper attacks

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.
