Littelfuse battery protectors provide fast response

Littelfuse has announced the ITV4030, a series of 22 amp, three-terminal, surface-mountable Li-ion battery protectors.

Measuring 4.0 x 3.0 mm these devices protect battery packs against overcurrent and overcharging (overvoltage) conditions. Their design uses embedded fuse and heater elements that provide fast response and reliable performance to interrupt the charging or discharging circuit before the battery pack becomes overcharged or overheated.

The ITV4030 Battery Protector is intended for use in a wide range of data communications interfaces for consumer electronics, including: tablets, power tools, robotic appliances, e-bikes and e-scooters and emergency radios and eCall

The ITV4030 offers a number of benefits:

  • Fast response time and low internal resistance help prevent battery pack damage caused by overcurrent and overcharging.
  • Surface mountable design simplifies automated PC board assembly processes.
  • Certifications from UL and TUV aid in securing approvals with meeting industry compliance requirements.
  • The environmentally friendly component is halogen-free and RoHS compliant.

An embedded three-terminal fuse 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.
