Broadcom Optocouplers for Safe Isolation

Intro - LC

Go with Opto!

Broadcom’s opto-isolation solutions provide unmatched high voltage protection and signal isolation that meet or exceed international safety standards. Broadcom optocouplers, including digital optocouplers, isolation amplifiers and gate drive optocouplers, are used in a broad array of applications ranging from power supply and motor control circuits to data communication and digital logic interfaces.

Tabs

The Broadcom digital optocouplers are versatile and easy to use to meet the industrial and factory automation applications of galvanic isolation. They have robust EMI/EMC immunity and excellent susceptibility performance. The small LED driving current and low supply voltage provides system’s power efficiency and long LED operating lifetime. These optocouplers have IEC 60747-5-5 component certification for reinforced insulation.
