The Path of Least Resistance
Upal Sengupta, Staff Applications Engineer
Texas Instruments – Battery Management Solutions
One (almost literal) “rule of thumb,” which I learned some years ago, was that if you couldn’t hold your finger on an IC for more than one second without feeling pain, the chip’s case temperature was probably above 50ºC. While I don’t recommend this technique as a substitute for doing actual thermal measurements on your PCB, it was an interesting discovery at the time… and of course it was also easier to do when IC packages were a little bigger than they are now.

"Good Vibrations"
Upal Segupta, Staff Applications Engineer
Texas Instruments
The word “resonance” has always been interesting to me, even when I couldn’t provide an accurate definition of it. There are so many different meanings, most of which have some connection to each other. As an electrical engineer, my first reaction at hearing the word now is to think of a tuned LC circuit.
