Example of recording unit storage power circuit

Circuit Description

Example of video recording unit storage power supply circuit block diagram

The surveillance camera must operate 24 hours, 365 days. For this purpose, the power never turn off, but the storage capacity of HDDs and SSDs used in the recording unit is limited. When the storage capacity approaches its limit, it is forced to be replaced, but it does not even power down, i.e. it is hot-swapped. Toshiba's eFuse IC help protect power lines from hot-swapping, routine power surges, etc. eFuse IC is equipped with various protective functions such as short-circuit, overcurrent, overvoltage, and inrush current suppression in a single package. It is useful for protecting equipment from surges such as overvoltage and overcurrent. eFuse IC is IEC62368-1 certified.

Examples of typical recommended products are listed below, and also provide a link to the online distributor inventory search page to buy the product.

Various protection features, such as high-speed short circuit protection, overcurrent clamp (OCC), overvoltage clamp (OVC), thermal shut down (TSD) and inrush current suppression are built in one package.
