Littelfuse, Inc., an industrial technology manufacturing company focused on sustainability, connectivity, and safety, has announced extending its ITV2718 surface-mountable Li-ion battery protector series. These fuses protect Li-ion battery packs from overcurrent and overcharging (overvoltage) conditions, even during fast charging.

The latest addition features a five-amp, three-terminal fuse in a 2.7 x 1.8 mm footprint. Its innovative design combines an embedded fuse and heater element, allowing it to respond quickly and interrupt the battery pack’s charging or discharging circuit before overcharging or overheating occurs.

The battery protector is suitable for various consumer electronics applications, including game consoles, e-call systems, routers, modems, smartphones, notebooks, and tablets.

The series offers key benefits, including preventing overcurrent and overcharging battery pack damage through its fast response time and low internal resistance. Its surface-mount design simplifies automated printed circuit board (PCB) assembly. It meets industry safety requirements with UL and TUV certifications, ensuring faster compliance approval. Additionally, the ITV2718 features environmentally friendly components that are halogen-free and RoHS-compliant.

“By extending our ITV line of li-ion battery pack protection fuses even further to include these new five-amp-rated devices, Littelfuse is providing electronics engineers even more options for their next-gen consumer electronics designs,” said Stephen Li, Global Product Manager at Littelfuse. “Continuing to expand our portfolio of surface-mountable, three-terminal battery pack protectors enables us to provide these product development teams with even greater, more innovative solutions in battery protection.”

The embedded three-terminal fuse immediately cuts off the circuit during an overcurrent condition. The heater element, located directly under the fuse element, generates sufficient heat to blow the fuse when the IC or FET detects overcharging.
