Electronic fuse protection integrated circuits are ideal for a wide variety of consumer electronics and data communication interfaces, including:

• Bluetooth headset
• Wearable devices
• Tablet
• Charging cable
• Battery equipment
• Adapter power supply device
• Network equipment
• Personal computer/laptop
• Data communication power supply system
• Fan power control
• HDD and SSD storage drives
• Industrial 12V/24 power input/output

Bernie Hsieh, assistant product manager of Littelfuse's Protected Semiconductor Business team, said, "Electronic fuse protection ics integrate powerful circuit protection, sensing and control into a single chip, providing great flexibility for today's electronics designers. Its ability to deliver low-power, high-precision current-limiting circuits with fast response times is a win-win-win for many portable electronics and data communication applications."

Electronic fuse protection integrated circuits have the following major advantages:

• Provides a highly accurate current limiter with faster response times and more integrated protection features than traditional fuses and PTC
• Greater flexibility than conventional power switches, such as adjustable overvoltage thresholds, current limits and surge currents, and true reverse current blocking
• Reduced time to design phase and time to market while reducing PC board space requirements and BOM costs compared to typical discrete solutions such as hot swap controllers + MOSFeTs
• Improve product reliability, extend battery life, reduce maintenance costs, and extend the overall service life of products
