Toshiba Launches 40V eFuse ICs For Power Line Circuit Protection
KUALA LUMPUR, Dec 9 (Bernama) -- Toshiba Electronic Devices & Storage Corporation (Toshiba) has expanded its electronic fuse (eFuse ICs) lineup with the new 40V TCKE6 series, adding five products designed to enhance power line circuit protection.
Shipments of the TCKE601RA, TCKE601RL, TCKE602RM, TCKE603RA, and TCKE603RL have begun.
The series delivers physical fuse-like short-circuit protection while adding current-limiting, overvoltage and thermal protection—capabilities standard fuses cannot provide.
In a statement, Toshiba said the integrated functions prevent excessive current or voltage from reaching downstream components and simplify circuit design by reducing the need for multiple discrete parts.
The TCKE6 series products feature a 40-volt (V) rating and support a wide input voltage range from 4.4V to 30V, making them suitable for power management applications, such as 5V, 9V, 12V, and 24V systems. A low on-resistance of 52 milliohms reduces power loss during operation and improves efficiency.
The eFuse ICs come in compact TSOP6F packages and are available with either FLAG or EN functions, along with auto-retry or latched recovery modes. Additionally, one model offers switchable recovery mode without FLAG or EN features, enabling flexibility for varying system designs.
Toshiba will continue to develop eFuse IC products that meet diverse equipment requirements and expand its product lineup.
