Avago's ACPL-M61T optocoupler

Avago Technologies has introduced the industry's first automotive-grade 10MBd digital interface optocoupler. Built to withstand high temperatures of up to 125C, Avago said its new ACPL-M61T is the only high-speed digital optocoupler available to support the stringent requirements of various networking, communication and system management applications within hybrid electric vehicles.

Temperature support of -40C to 125C makes the ACPL-M61T suitable for implementation in CANbus vehicle communication networks, battery management systems, safety and infotainment applications in all automobiles, including hybrid electric vehicles. Additionally, the product adheres to AECQ100 guidelines, ensuring manufacturers that Avago's optocouplers provide a consistent level of high-quality and reliability.

Due to the high number of electrical components in hybrid electric vehicles, opto-isolation products play a key role in the optimal performance of these cars. "Leveraging our extensive optocoupler expertise, we engineered the ACPL-M61T without compromise to quality and reliability, making the product suitable for automotive applications," said Kheng-Jam Lee, worldwide marketing manager of Avago Technologies' optical communication solutions division. This is the second product family targeting the emerging trend of hybrid electric vehicleswe will continue the momentum of developing new products for this growing automotive market."

The ACPL-M61T comes with an enhanced LED (5mA) for lower driving current and lower power consumption. The high-speed digital optocoupler also comes with enhanced wire bonding processes and an improved lead frame for added reliability and better heat dissipation. A high CMRR provides a high immunity to transient noises, EMI and ground loops eliminations. Its compact size also makes it flexible for high-density automotive system design.

Pricing for the ACPL-M61T starts at $2.50 in 10,000-unit quantities. It is shipped in leaded or Pb-free versions and with tape and reel options.
