Integrated Circuits
Integrated circuits (ICs) control, coordinate, and protect power supply circuits, diodes, phototransistors, shunt resistors, IGBTs, MOSFETs, and other power semiconductors. Types of ICs produced by Littelfuse include gate drivers, digital bus drivers, optocouplers, error amplifiers, high-voltage analog switches, voltage monitors, and digitally programmable capacitors. We also make ICs specifically engineered for use in telecommunications systems. Design options range from wafer fabrication and isolation barriers to multichip packaging and incorporation of overcurrent, overvoltage, overtemperature, and ESD protection.
