Littelfuse Adds ITV2718 5-Amp Rated Battery Protector Series

Littelfuse Adds ITV2718 5-Amp Extra Current Battery Maintainer Series to Prevent Damage to Li-Ion Battery Packs, the Next Generation of Smartphones, Gaming Consoles, and Other Consumer Electronics

Littelfuse Corporation (NASDAQ: LFUS) is an industrial technology manufacturing company dedicated to powering a sustainable, connected and safer world.

The company announced an expansion to its ITV2718 exterior unit lithium battery maintainer series. These fuses protect lithium battery packs from overcurrent and overcharge (overvoltage) conditions during rapid charging.

The newly introduced ITV2718 measures 2.7 x 1.8mm and supplies a 5-amp, three-terminal fuse.

This innovative design utilizes a combination of embedded fuses and heater elements to react quickly to interrupt the battery pack's charging or discharging circuits before an overcharge or overheating condition occurs.

The ITV2718 Battery Maintainer is suitable for a wide range of consumer electronics products, including:

● Game consoles

● Active emergency call systems

● Portable routers

● Portable modems

● Smartphones

● Laptops and tablets

“By further expanding our family of ITV lithium battery pack maintenance fuses to include these new devices with an additional current of 5 amps.

Littelfuse provides electronics engineers with more options for planning their next generation of consumer electronics.” Stephen Li, global product manager at Littelfuse, commented.

“Continuing to expand our portfolio of exterior device, three-terminal battery pack maintainers allows us to provide these product development teams with more robust and innovative battery maintenance solutions.”

The ITV2718 offers the following key benefits:

● Prevents battery pack overcurrent and overcharge damage through fast response time and low internal resistance; and

● External device planning simplifies active assembly of printed circuit boards (PCBs); ● UL and TUV certified.

UL and TUV certified to meet industry safety requirements to expedite compliance approvals; ● Halogen-free and compliant with industry standards.

Halogen-free and RoHS-compliant environmentally friendly components.

Principle of Operation

The embedded three-terminal fuse immediately blocks the circuit in the event of an overcurrent condition. The heater element is embedded directly under the fuse element and generates enough heat to blow the fuse once the IC or FET detects an overcharge.
