Today’s changing in the social environment, the purpose and applications have been expanded to public safety, disaster prevention, safety, etc., so constantly monitors through Internet connection utilizing image analysis technology have been expanding. With the expansion of Internet and high-speed large-capacity communication and the dramatic development of image processing technology, the transition from analog cameras to IP cameras (network cameras) advances, and storage and transfer in HD recording become possible, and it rapidly expands with low cost. Power management and signal quality are particularly challenging with highly functional surveillance cameras. By using MOSFET and high-performance, high-performance power management ICs that use Toshiba's newest processes, power management is realized to efficiently operate various functions with high-function LSIs. The lineup includes TVS Diodes (ESD Protection Diodes) and eFuse IC for protecting the internal circuitry from power-line failures.
