KAWASAKI, JAPAN--(Business Wire / Korea Newswire)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched a lineup of eight compact, high-voltage electronic fuses (eFuse ICs), the TCKE9 Series, that support multiple functions for the protection of power supply lines. Shipments of the first two products “TCKE903NL” and “TCKE905ANA” start today, with others to follow.

Even in the event of abnormal overcurrent or overvoltage, the specified current and voltage are maintained.

The new products also feature over-temperature protection and short-circuit protection, which protects a circuit by immediately shutting off the eFuse IC when abnormal heat is generated in the circuit or an unexpected short-circuit occurs. A further eFuse IC advantage is the elimination of complex circuit design and a reduced component count, realizing much simpler circuit designs with fewer components and a smaller area than is possible with a protection function secured with discrete parts.

Toshiba intends to obtain IEC 62368-1 certification, the international safety standard for high level safety, for the eFuse ICs, which will also simplify certification tests customers’ devices are required to undergo.

The product lineup offers eight products: four, 3.3V, 5V, 12V, 20V, are suitable for overvoltage protection of a range of power supply voltages, and each has two types - an auto-retry type, where the eFuse IC automatically recovers the circuit itself, and a latch type, where recovery is triggered by an external signal. Customers can select the appropriate product for their requirements and the size of their equipment.

Reference designs for an eFuse IC Application Circuit (with Thermal Shutdown) and an eFuse IC Application Circuit (with Enhanced Overcurrent Protection) are available now on Toshiba’s website.
