Toshiba Electronic Devices & Storage Corporation has recently stepped foot into the eFuse market with the launched its first-ever eFuse ICs lineup, the TCKE8xx series. According to reports, the new lineup will comprise of six products that would help protect circuit from fluctuating power supply lines. Moreover, these fuses can be used repeatedly, making them a better alternative to conventional physical fuses, chip fuses and glass tube fuses. For the record, conventional fuses protect power line circuits by shutting down physically when in an over-current state. These fuses break easily and require the need to be replaced. However, eFuse IC devices utilize their own circuitry to cut the power lines under any abnormality conditions and can be reused and reset. In addition to these advantages, eFuse ICs cut the need for complex circuit designs along with several components, providing simpler circuit designs with fewer components. It also takes up less space than a protection function which is protected by discrete parts. As per reports, the latest TCKE8xx Series offers robust circuit protection by increasing the level of over-current detection accuracy beyond physical fuses. Also, as eFuse ICs have voltage clamp and current clamp to shield against over-voltage and over-current, they can protect circuits and maintain power supply by clamping current and voltage at specified values. eFuse short-circuit and over-temperature protection functions shields circuits by immediately shutting off in the event of unexpected short-circuiting or extreme overheating. Sources suggest that the combination of these characteristics will allow the eFuse to help protect electronic equipment like Laptop, PCs and servers which have been required for handling increasingly higher withstand voltages and currents in recent years. Reportedly, TCKE8xx Series lineup would also provide two types of devices. First one being, a latch type that is recovered by an external signal and the second one being an auto-retry type that permits the eFuse to recover the circuit automatically.
