The innovative design provides fast response and reliable performance to interrupt the charging or discharging circuit before the battery pack becomes overcharged or overheated. Available in five compact, surface-mount packages, the Littelfuse ITV Series product line is available in current ratings of 12A, 15A, 30A and 45A.
“The ITV Series is an important addition to our li-ion battery protection portfolio, helping solve customer applications requiring current ratings from 12A to 45A,” said Stephen Li, Global Product Manager at Littelfuse.“Here’s how it works: An embedded fuse element cuts off the circuit when overcurrent issues occur. A heater element, directly embedded under the fuse element, generates enough heat to blow the fuse once overcharging is detected by IC or FET.”
This combination of robust overcurrent / overvoltage protection and surface mountable packaging is recommended for li-ion battery packs used in:
- Power tools
- Robotic appliances
- E-bikes and e-scooters
- Uninterruptable Power Supplies (UPS)
- Emergency radio and eCall
The Littelfuse ITV Series of battery protectors include these benefits:
- Innovative three-terminal fuse design protects against damage from both overcurrent and overcharging.
- Surface mountable form factor improves assembly efficiency.
- Low internal resistance minimises power loss.
- UL and TUV certifications aid compliance with industry standards.
- Environmentally friendly component is both ROHS compliant and halogen-free.
The ITV Series surface mount battery protectors are available in tape and reel format in quantities of 3,000. Sample requests may be placed through authorised Littelfuse distributors worldwide.
