Summary of FUNCTION-RICH RESETTABLE EFUSE FOR CONSUMER GOODS
Toshiba’s TCKE712BNL is a resettable eFuse IC for consumer electronics, offering adjustable over-voltage and over-current protection, over-temperature and short-circuit protection, reverse current blocking, a fault flag output, 53 mΩ on-resistance, 320 ns trip time, and a 4.4–13.2 V input range for reliable, reusable line protection across diverse devices.
Parts used in the TCKE712BNL eFuse project:
- Toshiba TCKE712BNL eFuse IC
- Power supply (4.4 V to 13.2 V)
- Protection circuitry connections for over-current, over-voltage, over-temperature, and short-circuit monitoring
- External flag signal connection
- Multiplexing system connections utilizing reverse current blocking
Resettable eFuse maintains high safety through repeated use with adjustable over-voltage protection plus flagging capabilities.
Expanding its range of advanced eFuse ICs, the TCKE712BNL from Toshiba Electronics Europe GmbH ensures that the highest degrees of safety are always maintained. It is targeted at a broad spectrum of different consumer electronics goods – including cameras, cordless cleaner and power tools, cleaning robots, server, smart, speaker, thermostats and wireless chargers.
While conventional fuses, such as glass tube and chip fuses, protect power supply lines by breaking if there is excessive current, eFuses provide a much more effective alternative. Unlike outdated conventional fuses, they are designed to support repeated use (being automatically reset by an internal logic signal). These devices also offer much faster responsiveness and have a greater breadth of built-in protection functions.
Exhibiting a 53 mΩ on-resistance and with a trip time of only 320ns, the TCKE712BNL covers an input voltage range spanning from 4.4 V to 13.2 V. It is possible to adjust this device’s over-voltage threshold to fit with the specific application requirements. In addition, over-current (also adjustable), over-temperature and short-circuit protection mechanisms have all been included. A flag function transmits an external signal that will alert engineers of possible faults in the circuit design, so they can be addressed early on in the development process. Thanks to the reverse current blocking feature, there is the scope for this device to be employed in multiplexed systems.
