Toshiba Releases 40V Electronic Fuses (eFuse ICs) for Industrial and Consumer Applications

KAWASAKI, Japan, Dec 9 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (”Toshiba”) has added the 40V "TCKE6 series" products to its range of electronic fuses (eFuse ICs) that support multiple functions required for power line circuit protection. The five new products joining the lineup are “TCKE601RA,” “TCKE601RL,” “TCKE602RM,” “TCKE603RA,” and “TCKE603RL.” Shipments start today.

The new TCKE6 series products offer short-circuit protection similar to that of standard physical fuses while also incorporating current limiting and overvoltage protection functions—capabilities that physical fuses[1] cannot provide and that protect circuits from overcurrent and overvoltage. These features help to prevent excessive current or voltage from being applied to subsequent ICs when overcurrent or overvoltage occurs at a point in a circuit. The eFuse ICs also have a built-in thermal protection function that immediately shuts them down when abnormal heat is generated or an unexpected short-circuit occurs, thereby protecting the subsequent circuit. An additional advantage of eFuse ICs is simplified circuit design. By integrating multiple protection functions into a single device, they reduce the need for discrete components, enabling more compact and efficient designs with fewer parts and a smaller footprint.
