Avago Technologies Introduces Two Automotive-Grade High Speed, Low Power Digital Optocouplers

New R2Couplers Ideal for CANBus Interface Isolation Apps, and Meet Stringent Automotive AEC-Q100 Grade 1 Qualifications

Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced a pair of automotive-grade high speed, low power, digital CMOS optocouplers for use in Hybrid Electric Vehicles. The ACPL-M71T single channel high speed 15MBd and ACPL-M72T low power LED drive optocouplers are the latest additions to Avago’s R2Coupler™ digital family. Both of these high temperature, low power optocouplers, which are available in small outline IC-5 (SOIC-5) packages, are ideal for use in controller area network bus (CANBus) interfaces and microcontroller interfaces applications.

Avago’s ACPL-M71T and ACPL-M72T R2Couplers incorporate the latest CMOS IC technology to achieve superior performance to provide reinforced insulation and reliability that delivers the level of safe signal isolation that is critical in automotive and high temperature industrial applications. The design of the IC provides excellent electrostatic discharge (ESD) performance of 4kV Human Body Model (HBM) and 400V Machine Model (MM) to meet the design requirements of automotive electrical systems. Additionally, these digital optocouplers are qualified to the automotive AEC-Q100 Grade 1 component stress test guidelines and are manufactured under TS16949 automotive quality standards.

Both the ACPL-M71T and ACPL-M72T use a proprietary LED technology with lower driving current and lower power consumption for high speed 15MBd and low speed digital applications.
