How does overcurrent protection enable longer lifecycles?
One key to preventing damage in modern electronic systems is the ability to rapidly detect and react to potentially damaging conditions. Accurate and precise overcurrent detection is one method for successful damage prevention. Thermal management in modern electronics, whether the newest smart phone or the largest industrial machine, has become vitally important as two industry trends take hold.
The first is the desire for more performance. Today’s electronics have processing power in orders of magnitude more than their predecessors just since the early part of the millennium! The second is the desire for even smaller form factors.
Historically, temperature has been used to manage the thermal protection of these systems. In many systems today, rather than measuring the lagging indicator (temperature), current (or the power which is the voltage times the current) is being measured, which is a leading indicator for thermal increase.
