Sensata. In advanced battery systems, the quality of the power electronics helps determine the quality of the final product, its level of functionality, and its reliability. This is emphasized in the latest battery power management and charging systems that use wide-bandgap semiconductors and improved power topologies. In such advanced electronics, if the safety systems do not work quickly and reliably, the entire battery system can suffer a catastrophic failure that could seriously impact the product and its user. The GigaFuse trips circuits at exact, specified currents.
