Power Protection

External ESD, abnormal input power, and hot-plug surges are often problems with the power supply. Protection of valuable data from these damages is required in the design.

Toshiba's eFuse IC realizes ultra-high-speed short-circuit protection, and has various protection functions such as overcurrent, overvoltage and inrush current suppression in a single package. In addition, since it has IEC62368-1 (G.9) compliance, it is possible to design a protective circuit simpler and stronger than before.

Toshiba's high-IPP TVS diodes (ESD-protection diodes) and Zener diodes can also be used to suppress from a few ns-order to ms-order ESD and transient voltages. In addition, when combined using with the SBD, a more robust protection circuit can be realized as a countermeasure against negative voltage and reverse current.

When an excessive current flows, the internal detection circuit operates and the built-in MOS is turned off, thus providing a high-speed current breaking function for conventional fuses. Furthermore, it is not destroyed by a single overcurrent, and can be used repeatedly. It also has the advantage that it can incorporate a variety of protection functions such as overvoltage protection. This product is also effective in reducing maintenance costs and restoration time required for repairs.

Preventing damage or malfunction of the device due to external surge voltage, wide line-up of protection diodes ranging from one line to four lines is available in a small package, and high ESD tolerance and circuit protection performance realized by original process technology.

Superior low-VF and low-IR types ranging from general-purpose to high-power products. Schottky Barrier Diodes can contribute to high power efficiency and power saving of various devices.
