Various types of power tools are marketed for a wide range of applications, from household to professional use. Recently, the adoption of high-capacity lithium-ion batteries has led to a shift to cordless types that are compact, light, easy to carry, and easy to work with, not only for household use but also for professional use, such as hammer drills, impact wrenches, nailers, staplers, and round saws. The capability of cordless power tools to operate for longer time periods with a single charge is one of the major qualities for users when choosing products. Toshiba's lineup of MOSFET, motor control drivers, photocouplers, and other products that use current technologies helps designers make efficient use of limited battery capacities.
