The innovations that vendors presented at Electronica 2010 ran the gamut from ICs and components to test-and-measurement equipment. Manufacturers presented circuit-protection devices that might, at first glance, seem important yet less eye-catching than, for example, multicore DSPs. Nevertheless, Tyco Electronics presented a couple or sucn devices worth a closer look.Low-power devices often find their way into battery-powered products, which require protection from overcurrent situations that could damage the battery and lead to safety problems. Tyco is addressing such applications with an MHP (metal-hybrid-polymetric-positive-tem-perature-coefficient) device that protects lithium-ion batteries in high-power applications, providing bimetal protection with built-in arc-suppression technology. It addresses applications such as those involving consumer power tools in which a drill bit gets stuck, resulting in a potentially damaging overcurrent condition.
