Overview

Broadcom optocouplers can be used in an array of isolation applications ranging from power supply and motor control circuits to data communications and digital logic interface circuits in both industrial and automotive markets. The primary purpose of an optocoupler is to provide both electrical insulation (safety) and signal isolation (reliability). Optocouplers eliminate the effects of electrical noise caused by crosstalk, power glitches and electrical interference. They provide high voltage isolation allowing safe interface between high and low voltages in electrical circuits and are also used for shifting logic levels. Key Broadcom products include optocouplers with digital and analog output, high speed and high gain performance, drivers for isolated gate transistors, MOSFETS and intelligent power modules, smart current sensors and other application-specific devices. When selecting the correct product to use in isolation applications, it is important for designers to understand safety and performance relevant features to guarantee optimum reliability over the lifetime of their products. This presentation will specifically cover the topics of LED degradation, insulation ratings, aging mechanisms and the effects of ESD and high voltage surges. It will also include a short overview of the current Broadcom isolation portfolio and key new product introductions.
