Littelfuse Expands eFuse Protection ICs Series to Address More Diverse and Demanding Applications
March 20, 2023
Littelfuse, Inc. announced the latest release of four versatile circuit protection devices in the eFuse Protection ICs product line.
The latest eFuse Protection ICs utilize an innovative design ideal for a wide range of power inputs (3.3V to 28V) with highly integrated protection. These semiconductor-based electronic fuses provide robust overvoltage, overcurrent, short circuit, and inrush current protection. Additional features include reverse current blocking, under voltage lockout (UVLO), soft start, and overtemperature protection with real-time diagnostics—all in one compact chip. View the video.
The latest eFuse Protection ICs are ideal for use in a wide range of electronics designs, including:
| 5V Applications | 12V Applications | 24V-28V Applications |
| Portable electronics | SSD/HDD | USB Type-C PD |
| Bluetooth devices | Switch routers | Power tools |
| Wearables | Enterprise servers | Industry |
| Smartphones | Fan0 systems | PLC |
| USB Type-C cables | Telecom | POS |
| Internet of Things (IoT) | Appliances | Building |
“The expanded eFuse Protection ICs product line delivers clear performance advantages for electronics designers,” said Bernie Hsieh, Assistant Product Manager of the Protection Semiconductor Business team at Littelfuse. “Compared to traditional fuse, PTCs, power switches, and discrete solutions like Schottky diode and MOSFET combinations, the eFuses provide exceptional integration, adjustability, flexibility, and reliable protection features in highly compact form factors that save PC board space.”
