Thermal protection is very important in many power systems. Figure 1 shows a low-cost thermal-protection circuit based on the LTC1998, a 6-pin SOT-23 comparator for battery monitoring. This circuit ...

Understanding the advantages, limitations, and use cases of each technology helps engineers create reliable consumer products.

ICs with a temperature protection function, the smallest number of external components in the industry and the industry’s smallest class of packages improve safety and reduce circuit board size TOKYO- ...

You can use several circuit protection schemes in power supplies to help guard against fault conditions and the resultant overtemperature damage, including thermal fuses, current fuses, and circuit ...

Motors differ from other types of loads in one important way: The motor needs much more current to start than to run. This temporary, but significant, inrush current is what complicates motor circuit ...

Security and fire alarm systems are designed for operation within specified current and voltage ratings. If these ratings are exceeded due to short-circuit or voltage transients, components may ...

During normal operation, thermal circuit breakers utilize a thermal sensing element (such as bimetal), which deflects when the temperature reaches a predetermined calibration level, causing the ...

It’s Friday night and a frantic call from the operations vice president wakes the chief engineer in the middle of the night. “Our factory is down!” the VP cries out. Apparently, there was a heavy ...

Guest columnist Faraz Hasan, marketing and business development manager at Tyco Electronics Circuit Protection Products says that LEDs can require overcurrent protection despite built-in safety ...

In Part 1, we looked at how to size a branch circuit and walked through a simple example. So if you’re sizing a feeder, why don’t you do it the same way? Except in cases where a feeder is also ...
