The ITV2718 surface-mountable Li-ion battery protector series from Littelfuse has been extended. Even during fast charging, these fuses protect Li-ion battery packs against overcurrent and overcharging (overvoltage) situations.
The newest addition, the ITV2718 surface-mountable Li-ion battery protector series, has a three-terminal, five-amp fuse with a footprint of only 2.7 x 1.8 mm.
The creative design responds swiftly, cutting off the battery pack’s charging or discharging circuit before overcharging or overheating circumstances arise. The new surface-mountable Li-ion battery protector series does this by combining an inbuilt fuse and heater element.
Applications for the ITV2718 Battery Protector in consumer electronics are wide, including:
- Game consoles
- E-call
- Portable routers
- Portable modems
- Smartphones
- Notebooks and tablets
“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 Surface-Mountable Li-ion Battery Protector Series offer These Key Benefits:
- Surface-mount design facilitates automated printed circuit board (PCB) assembly;
- Fast response time and low internal resistance prevent overcurrent and overcharging battery pack damage.
- For quicker compliance clearance, UL and TUV certifications demonstrate conformity with industry safety standards.
- Environmentally friendly, RoHS-compliant, and halogen-free components.
How It Works
In the event of an overcurrent, the inbuilt three-terminal fuse instantly cuts off the circuit. When the IC or FET senses overcharging, the heater element—which is implanted just beneath the fuse element—produces enough heat to blow the fuse.
Availability
