Littelfuse extends ITV9550 battery protector series to include 60 A current rating to prevent battery pack damage
Littelfuse Corporation, an industrial technology manufacturing company committed to powering a sustainable, connected and safer world, announced the expansion of its ITV9550 line of surface-mounted lithium battery protectors. These fuses protect the battery pack from overcurrent and overcharge (overvoltage) conditions.
The new ITV9550 is a 60 amp, three terminal fuse with a size of 9.5 x 5.0 mm. The innovative design incorporates a built-in fuse and heater assembly for fast response and reliability to disconnect the battery pack's charging or discharging circuits before overcharging or overheating conditions occur.
The ITV9550 Battery Protector is ideal for use in a wide range of consumer electronics including:
● Power tool
● Robotic equipment
● Electric bicycles and electric scooters
● Emergency radio
● Uninterruptible power supply (UPS).
Stephen Li, global Product Manager for Littelfuse, said, "The new release of parts for 60-amp devices expands our ITV line of lithium battery protective fuses to provide more options for electronics designers. Expanding our portfolio of surface-mounted, three-terminal electronic block protectors allows us to deliver this innovative solution to a wider range of consumer and industrial applications."
The ITV9550 provides the following key benefits:
● Fast response and low internal resistance to prevent overcurrent and overcharge caused by battery pack damage.
● Using surface mount design, simplify automatic printed circuit board (PCB) assembly process.
● UL and TUV certifications help obtain approvals that meet industry compliance requirements.
● Environmental protection components do not contain halogen, in line with RoHS standards.
Working principle: In case of overcharge, the built-in fuse with three terminals can cut off the circuit. The heater assembly is embedded directly under the fuse assembly to generate enough heat to blow the fuse if the IC or FET detects the process condition.
