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.

A New Method for Maintaining the Charge of VRLA Batteries in Telecommunications Standby Systems
David P. Boden
Encell Technology, Inc.
Standby battery systems have been an essential part of modern life for many years. Initially used to support the telephone system by the Bell Telephone Company they have now become necessary in virtually every walk of life. Batteries are used in series strings to provide a matching voltage with the load and they can be connected in parallel to provide the necessary capacity for the required backup time.
