Business WireKAWASAKI, Japan — 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.”THIS CONTENT IS RESERVED FOR SUBSCRIBERS ONLYSubscribe now to read the latest news in your city and across Canada.Exclusive articles from Barbara Shecter, Joe O'Connor, Gabriel Friedman, and others.Daily content from Financial Times, the world's leading global business publication.Unlimited online access to read articles from Financial Post, National Post and 15 news sites across Canada with one account.National Post ePaper, an electronic replica of the print edition to view on any device, share and comment on.Daily puzzles, including the New York Times Crossword.SUBSCRIBE TO UNLOCK MORE ARTICLESSubscribe now to read the latest news in your city and across Canada.Exclusive articles from Barbara Shecter, Joe O'Connor, Gabriel Friedman and others.Daily content from Financial Times, the world's leading global business publication.Unlimited online access to read articles from Financial Post, National Post and 15 news sites across Canada with one account.National Post ePaper, an electronic replica of the print edition to view on any device, share and comment on.Daily puzzles, including the New York Times Crossword.REGISTER / SIGN IN TO UNLOCK MORE ARTICLESCreate an account or sign in to continue with your reading experience.Access articles from across Canada with one account.Share your thoughts and join the conversation in the comments.Enjoy additional articles per month.Get email updates from your favourite authors.THIS ARTICLE IS FREE TO READ REGISTER TO UNLOCK.Create an account or sign in to continue with your reading experience.Access articles from across Canada with one accountShare your thoughts and join the conversation in the commentsEnjoy additional articles per monthGet email updates from your favourite authorsSign In or Create an AccountThis advertisement has not loaded yet, but your article continues below.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.Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

Please try againTCKE5 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 (IOCP) can be set using an external resistor (RILIM), 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 IOCP flows, the output is shut off after the mask time tOCP.Protection of power supply circuits in USB devices, HDMI® devices, laptop PCs and gaming consoles.Input voltage operating range: 1.7V to 5.5V, supporting 1.8V, 3.3V, and 5V power linesOvercurrent protection mask time: tOCP = 2.4ms (typ.)Thin and compact SOT-353F package: 2.0×2.1×0.7mm (typ.)This advertisement has not loaded yet, but your article continues below.(Unless otherwise specified, VIN=3.3V, RILIM=13.3kΩ, RLOAD=100Ω, CIN=COUT=1μF, Ta=25°C)Part numberTCKE501UATCKE501ULTCKE502UATCKE502ULFault responseAuto-retryLatchedAuto-retryLatchedAbsolute maximum ratingInput voltage VIN (V)-0.3 to 6.0Operating rangeInput voltage VIN (V)1.7 to 5.5[2]Operating junction temperature Tj_opr (°C)-40 to 125Output current IOUT (A)DC0 to 1.0Pulse0 to 2.0[3]Electrical characteristicsOn-resistance[4] RON (mΩ)VIN= 1.7 to 5.5V, IOUT=1.0ATyp.75Max100Overcurrent protection threshold[4] IOCP (A)RILIM＝ 6.8kΩ, Ta=-40 to 125°CMin0.88Max1.12Overcurrent Protection mask time[5] tOCP (ms)IOUT= 0 to 1.5ATyp.2.4Fast trip comparator level[5] ISHORT (A)Typ.2.8Short circuit response time[5] tSHORT(µs)IOUT>ISHORT→IOUT＝０ATyp.1.3Switching characteristics[5]Turn on rise time tR(µs)VIN=1.8VTyp.400750VIN=3.3VTyp.6001150VIN= 5.0VTyp.8001450PackageNameSOT-353F (UFV)Size (mm)Typ.2.0×2.1×0.7Sample check & availabilityBuy OnlineBuy OnlineBuy OnlineBuy Online[2] Section 16 of the datasheets details precautions to be taken when using the product.
