New eFuse protection devices operate over wide voltage range
Littelfuse has announced four versatile new eFuse ICs which provide a comprehensive set of protection functions for electronics circuits. Highly integrated, the eFuse ICs enable developers to reduce design time and save board space and bill-of-materials cost when compared to typical discrete solutions such as a combination of a hot-swap controller and MOSFET.
Littelfuse eFuse ICs ideal for consumer electronics, data communications and industrial applications.
The eFuse products, which operate over a wide voltage range of 3.3 V up to 28 V, offer the over-voltage protection of a standard fuse. But in addition, the fuses protect against over-current, short-circuit, inrush current, reverse current, and over-temperature events while supplying real-time diagnostic data.
The eFuse ICs are ideal for use in the protection of consumer electronics and data communications interfaces.
