Littelfuse introduced a new line of electronic fuse protection integrated circuit products, which will include four multi-functional circuit protection devices. The electronic fuse protection integrated circuit adopts an innovative design, which can provide a wide power input range (3.3V to 28V) and integrated protection. In addition to over-voltage protection, this series of electronic fuses can also prevent over-current, short circuit, surge current, reverse current and overheating events, and have real-time diagnostic functions - all functions are implemented in one chip.
"The electronic fuse protection IC integrates powerful circuit protection, sensing and control into one chip, providing great flexibility for today's electronic designers." Bernie Hsieh, Assistant Product Manager of Littelfuse Protection Semiconductor Business Team, said, "It can provide low-power, high-precision current limiting circuit with fast response time, which is a win-win solution for many portable electronic products and data communication applications."
Electronic fuse protection of integrated circuit has the following main advantages: compared with the traditional fuse and PTC, provides a highly accurate current limiter, and has faster response time and more integrated protection function compared with the traditional power switch with greater flexibility, such as adjustable over voltage threshold, current limit and surge current, and the real reverse current block
Compared to typical discrete solutions such as hot-swappable controller +MOSFET, this reduces time to design phase and time to market while reducing PC board space requirements and BOM costs. Improve product reliability, extend battery life, reduce maintenance costs, and extend the overall service life of products
