Littelfuse Inc., a manufacturer of circuit protection, power control and sensing solutions, has unveiled the ITV series, a three-terminal, surface mountable lithium-ion battery protector designed to guard against the damage caused by both overcurrent and overcharging. The innovative design provides fast response and

Available in five compact, surface-mount packages, the Littelfuse ITV series product line is available in current ratings of 12 A, 15 A, 30 A and 45 A.
According to the company, 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 field-effect transistor.
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 key benefits:
- Innovative three-terminal fuse design protects against damage from both overcurrent and overcharging.
- Surface mountable form factor improves assembly efficiency.
- Low internal resistance minimizes 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 authorized Littelfuse distributors worldwide.
