The new eFuse Protection ICs Series features protection, sensing, and control features in a single chip. 

CHICAGO. Littelfuse, Inc. released the eFuse Protection ICs product line providing a power input range from 3.3V to 28V and four circuit security components with  low energy consumption. Integrated into the eFuse Protection IC is a current timer and protection against overvoltage, overcurrent, short circuit, inrush current, reverse current, and overtemperature issues with real-time diagnostics.

“The eFuse Protection ICs provide today’s electronics designers with significant flexibility by integrating robust circuit protection, sensing, and control in a single chip,” said Bernie Hsieh, Assistant Product Manager of the Protection Semiconductor Business team at Littelfuse.

The eFuse Protection IC minimizes PC board space as well as speed up design and lower production time by utilizing a hot-swap controller + MOSFET.

Littelfuse designed its eFuse Protection ICs for a use in an array of data communications interfaces and consumer electronics including:

• Bluetooth headsets
• Wearable devices
• Tablet PCs
• Charging cables
• Battery devices
• Adapter-powered devices
• NetworkingPCs / notebooks
• Datacom power systems
• Fan power controlsHDD and SSD storage drives
• Industry 12V/24 power input/output

According to Littelfuse, the eFuse Protection ICs are available in the following varieties:

• LS0504EVT233 – 5V, 4A, overvoltage, overcurrent protection, SOT23-3 package
• LS0505EVD22 – 5V, 5A, overvoltage, overcurrent protection, DFN2x2 package
