What Is Motorola Droid-X eFuse Security System? – …

The Motorola Droid-X contains a freshly installed security system called eFuse. The Android phone contains an eFuse chip on the board where Motorola can write information to after it is put to use. Motorola uses information from the bootloader that is passed on and gets written over this eFuse chip.

Toshiba Releases its First eFuse, an Electronic Fuse that …

 · The most remarkable feature of the eFuse ICs is that they can be used repeatedly. Conventional physical fuses—glass tube fuses and chip fuses—protect power line circuits by physically shutting them down when they are in an over-current state, and are needed to be replaced once broken. eFuse IC products use their own circuitry to shut power lines down when an abnormality occurs, and …

Why use an e-fuse? Part 1 Frequently Asked Questions

This FAQ will explore the electronic fuse (commonly called an e-fuse or efuse) and the characteristics of the current-sense amplifier (CSA) that is needed to make it a reality. Fig 1: The well-known thermal fuse I available in a huge selection of physical sizes and package types, based on current ratings and application requirements (Image source: ElectricalTechnology.org )
