Battery protector series to prevent Li-ion battery pack damage
Littelfuse has expanded its ITV2718 line of surface-mount lithium-ion battery protectors. These fuses protect the lithium-ion battery pack from overcurrent and overcharge (overvoltage) - even during fast charging.
The latest addition, the ITV2718, offers a 5A, three-terminal fuse with a footprint of 2.7mm x 1.8 mm. The innovative design uses a combination of embedded fuses and heating elements for fast response to interrupt the battery pack's charging or discharging circuit before an overcharge or overheating situation occurs.
Battery protectors are suitable for a wide range of consumer electronics applications, including game consoles E-call, portable routers, portable modems, smartphones, laptops and tablets.
Stephen Li, global Product Manager at Littelfuse, said: "By further expanding our range of ITV lithium-ion battery pack protection fuses to include these new 5-amp devices, Littelfuse offers electronics engineers even more design options for the next generation of consumer electronics." "Continuing to expand our portfolio of surface-mount three-terminal battery pack protectors allows us to offer larger, more innovative battery protection solutions to these product development teams."
The embedded three-terminal fuse cuts off the circuit immediately in case of overcurrent. The heating element is embedded directly under the fuse element and generates enough heat to burn the fuse once the IC or FET detects an overcharge.
