CHICAGO – Littelfuse Inc. in Chicago is introducing the ITV4030 series of 22 amp, three-terminal, surface-mountable lithium-ion battery protectors for tablet computers, robotic appliances, and emergency radios.
These 4-by-3-millimeter devices protect battery packs against overcurrent and overcharging. They use embedded fuse and heater elements that interrupt the charging or discharging circuit before the battery pack becomes overcharged or overheated.
The power electronics devices offers a surface-mountable design; certifications from UL and TUV; and 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.
