Power line protection circuit with the eFuse IC, TCKE805x Series
Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched the "TCKE8xx series," its first-ever eFuse ICs, a lineup of six products that support various functions needed for circuit protection in power supply lines.
eFuse ICs can interrupt a power supply with higher current accuracy and in a shorter time than tubular glass fuses and polyswitches (also known as resettable fuses and polyfuses). If a tubular glass fuse burns out, it must be replaced after removing the factors that cause excessive current. In contrast, eFuse ICs are free from the drawbacks of conventional fuses since they are composed of a MOSFET that interrupts a power supply and various protection functions. Without being susceptible to permanent destruction, eFuse ICs eliminate the need for fuse replacement and enhance system reliability.
Features
- Over current limit accuracy : ±11 % ＠Ta= -40 °C to +85 °C, ILIM=4.38 A
- High-speed short circuit protection : tFastOffDly=150 ns (typ.) ＠Ta= -40 °C to +85 °C
- High output current : IOUT=0 A to 5.0 A
- Thin and compact package : 3.00×3.00 mm (typ.), t=0.75 mm (max)
Applications
- Circuit protection of IoT circuitry power supply lines
(Servers, SSDs, laptop PCs, game consoles and augmented reality and virtual reality equipment, etc.)
Key Components
- eFuse Ics
Benefits
- servers and laptop PCs, which have been required for to handle increasingly higher withstand voltages and currents in recent years. As Toshiba intends to obtain IEC 62368-1 certification, the international safety standard for high level safety, they will also simplify the certification tests customers’ devices are required to undergo.
