CHICAGO – Littelfuse Inc. in Chicago is introducing the eFuse Protection series of four circuit-protection devices to protect against overvoltage, overcurrent, short circuits, inrush currents, reverse currents, and overtemperature, all in one chip.
The eFuse Protection integrated circuits provide power input ranging from 3.3 to 28 volts, and are for wearable devices; charging cables; battery devices; data communications power systems; fan power controls; and data storage drives.
The eFuse Protection integrated circuits offer current limiter, with fast response time, and integrated protection features; adjustable overvoltage threshold, current limiting, and inrush current; a reduction in the design-in phase; improved reliability; increased battery life; and long overall product lifetime.
The LS0504EVT233 is a 5-volt, 4-amp, overvoltage, overcurrent protection in a SOT23-3 package; the LS0505EVD22 is a 5-volt, 5-amp, overvoltage, overcurrent protection in a DFN2x2 package; the LS1205ExD33 is an 18-volt, 5-amp, programmable current limit, output voltage clamp in a DFN3x3 package; and the LS2406ERQ23 is a 28-volt, 6-amp, true reverse blocking, fast role swap in a QFN2.5x3.2 package.
The eFuse Protection power integrated circuits are available in tape and reel format in quantities of 3,000 (LS0504EVT23, LS0505EVD22) or 5,000 (LS1205ExD33, LS2406ERQ23).
