Toshiba TCKE712BNL eFuse IC

Toshiba Electronic Devices & Storage has added the TCKE712BNL to its line-up of eFuse ICs for repeated use, which supports functions to protect power line circuits. It can be used in laptops, game consoles, augmented reality and virtual reality equipment, smart speakers, robot cleaners, networking servers, etc.

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 once used and broken must be replaced. eFuse ICs are designed to replace such fuses in providing power line circuit protection and safety, and to deliver a range of built-in protection functions in addition to overcurrent protection.

The TCKE712BNL protects power lines with an overvoltage protection function that can be adjusted to user requirements with external resistors. It also has a built-in reverse blocking current function in the OFF state, allowing use in power multiplexer applications. In addition, its built-in protection functions cover overcurrent, short-circuit and overtemperature. It also has a FLAG function that transmits an external signal if an abnormality occurs in the circuit, which should make it easier to detect possible faults than with Toshiba’s current products.
