Smart speakers technology are dramatically improve with speech recognition technology connecting Internet, Cloud big data and AI. Additionally today, smart speakers have displays, sensors and cameras to become home network hub equipment. For this purpose, we expect to continue adding various functions to smart speakers. Toshiba offers a lineup of power management ICs with very tiny package, such as LDO regulators and load switch ICs to efficiently operate complex electronic circuits. eFuse IC and other power management ICs for protecting from power line abnormalities, and TVS diodes (ESD protection diodes) for protecting various interfaces. These semiconductors contribute to improve performance and reduce of body size of smart speakers.
