KAWASAKI, Japan--(BUSINESS WIRE)--Oct 12, 2026--
Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched a lineup of four electronic fuses (eFuse ICs), the TCKE5 Series, that integrate multiple functions for the protection of power supply lines. Shipments start today. The new products operate over an input voltage range of 1.7V to 5.5V and are housed in the small SOT-353F (UFV) package. The lineup consists of four products, “ TCKE501UA,” “ TCKE501UL,” “ TCKE502UA,” and “ TCKE502UL.”

The miniaturization, enhanced functionality, and lower power consumption of electronic equipment have increased the use of applications that require low-voltage power supplies, including 1.8V power lines. To improve system reliability, protection functions against overcurrent and short-circuit conditions are also required for low-voltage power lines.
TCKE5 Series products feature an operating input voltage range of 1.7V to 5.5V and are the first products in Toshiba's eFuse IC lineup to support 1.8V power lines. This makes them suitable for low-voltage applications, including SD memory cards.
The series is available in the small, low-profile SOT-353F (UFV) package, which helps reduce PCB mounting area and contributes to space-saving and high-density designs for products such as wearable and IoT devices.
In addition to the short-circuit protection provided by physical fuses, such as glass tube fuses and chip current fuses, the TCKE5 Series incorporates overcurrent protection that shuts off output when overcurrent is detected. The overcurrent detection threshold (I OCP ) can be set using an external resistor (R ILIM ), enabling protection levels to be configured to meet system requirements. Overcurrent protection also includes a mask time [1] that helps prevent unnecessary shutdowns caused by transient peak currents. These features help protect downstream circuits and contribute to improved system safety and reliability.
The product lineup includes both an auto-retry type, where the eFuse IC automatically recovers circuit operation, and a latch type, where recovery is triggered by an external signal, and customers can select the appropriate product for their system configuration. The series also offers products with different slew-rate settings, and customers can choose a device that meets their power sequencing requirements.
Toshiba will further expand its eFuse IC lineup with products that support a wide range of equipment.
Note:
[1] When a current exceeding the overcurrent detection threshold I OCP flows, the output is shut off after the mask time t OCP.

Toshiba: TCKE5 Series of small-package eFuse ICs supporting 1.7V low-voltage operation.
BANGKOK (AP) — The International Monetary Fund on Tuesday slightly upgraded its outlook for the world economy for this year, while warning of growing risks from rising debt, including borrowing related to artificial intelligence.
The IMF says it expects the global economy to grow at a 3.1% pace this year. That's up from its July forecast for 3.0% growth and well below the 3.5% expansion in 2025. Growth in 2027 should rebound to 3.4%, it said in its latest Economic Outlook.
The report, released as world economic and financial leaders gather in Bangkok for the fall meetings of the IMF and World Bank, predicts that growth in the United States will remain steady at 2.3% in 2026 and 2027.
Collectively, advanced economies will grow 2.1% this year, up from 2.0% in 2025. But growth is forecast to slow to 1.9% next year, it said.
The forecasts are based on a nearly 41% increase in oil prices this year, at an average of $96 a barrel. Global inflation is foreseen at 4.7% in 2026, falling to 4.1% next year. They also are based on the assumption that shipments of oil and gas through the Strait of Hormuz will resume by March, and that the boom in AI demand will moderate.
The boom in artificial intelligence is offsetting damage from sharply higher prices for oil and gas, IMF economists say, but it also carries risks.
Its benefits are not shared equally: the U.S. and China account for more than three-quarters of net demand for imports of computer chips and other AI-related equipment, the report said.
“The outlook is highly uneven,” Silvana Tenreyro, the IMF's director of research, told reporters in Bangkok.
Growth is increasingly concentrated, with 32 countries accounting for 95% of global growth, the report said. That compares with 54 countries as of April.
“The global economy is not simply slowing or accelerating; rather, growth is being reallocated across countries according to their exposure to the war-induced supply shock and AI-related demand strength,” it says.
Athanasios Vamvakidis, deputy director at the IMF's Monetary and Capital Markets Department, said an AI-related correction in stock markets is just one of the risks. Rising bond yields are another evolving problem, along with cyberthreats that could disrupt financial systems, he said.
AI's effects on employment are another key focus of the meetings in Bangkok, which IMF Managing Director Kristalina Georgieva described during an event Monday as “a slow moving tsunami, but a tsunami nonetheless."
"The impact over time on jobs globally we estimate to be around 40% — jobs either augmented or downgraded or eliminated. And we are already seeing some of this impact,” she said.
Last week, the IMF chief urged countries both rich and poor to do a better job of improving their national finances, urging policymakers to do more to tame mounting levels of debt.
That's especially true at a time of high borrowing costs, Tenreyro said.
Countries that are somewhat insulated from the energy shocks of the Iran war and that are benefiting from rapid adoption of AI are managing to keep growth on track. But developing economies and emerging markets more vulnerable to higher costs for oil and gas will see growth slow to 3.7% this year from 4.5% in 2025, the report says. It forecasts they will regain momentum next year, expanding at a 4.4% annual pace.
The situation is much worse in the Middle East and Central Asia, where those regions' economies are expected to contract this year before recovering to a 6.3% rate of growth in 2027.
The 21 European countries that share the euro currency are expected to grow by 1.1% this year and 1.2% in 2027.
China, the world’s No. 2 economy, is expected to expand 4.5% this year, down from 5% in 2025, in line with the government's official target.
India is once again forecast to be the world’s fastest-growing major economy, advancing at a 7% clip, down from a sizzling 7.7% last year.
The IMF is a 191-nation lending organization that works to promote economic growth and financial stability and to reduce global poverty. At the meetings in Bangkok, finance ministers and central bank governors will assess the state of the world economy and discuss strategies to support financial stability and sustained growth.
