Avago Technologies adds automotive-grade dual-channel optocouplers for bi-directional digital communications

Avago Technologies (NASDAQ: AVGO), a leading supplier of analog interface components for wireless, wireline, storage and industrial applications, announced a new family of dual-channel R² Coupler optocoupler devices, the ACFL-521xT and ACFL-621xT, designed for automotive applications with AEC-Q100 Grade 1 qualification. The ACFL-521xT is optimized for low power systems supporting data rates up to 1 MBd, and the ACFL-621xT is optimized for high speed systems supporting data rates up to 15 MBd.

Expanding upon previous generation R² Coupler ACPL-KxxT devices, the ACFL-521xT and ACFL-621xT devices have two optocoupler channels internally aligned 180 degrees of each other, thereby providing optimum chip pin-out configuration for bi-directional Tx/Rx data communication design and board layout. Furthermore, the two channels are electrically independent and galvanically isolated, providing an ideal isolated bi-directional low power communication interface. The devices feature 8mm wide creepage and clearance, high dielectric breakdown isolation voltage (V_ISO ) up to 5,000 V_RMS  for one minute, and high continuous working voltage (V_IORM ) up to 1,140 V_PEAK . The devices are packaged in a compact SSO-12 package comparable to the SSO-8 footprint of previous generation devices.

New Product Highlights

• Automotive Qualified per AEC-Q100 Grade 1 Test Guidelines
• Operating Temperature from -40 °C to +125 °C
• Chip Pin-out Optimized for Bi-directional Digital Communications
• Dual-channel Optocouplers in Compact SSO-12 Package Minimizing PCB Board Space and Cost
• 20kBd to 1MBd Data Rates with Low Power Consumption (ACFL-521xT)
• 10 to 15MBd Data Rates with CMOS Outputs & Propagation Delay < 35 ns (ACFL-621xT)
• UL 1577 Certified for V_ISO  = 5,000 V_RMS , 1 Minute Rating
• IEC/EN/DIN EN 60747-5-5 Certified for Reinforced Insulation, V_IORM  = 1,140 V_PEAK

Avago will be showcasing the ACFL-521xT and ACFL-621xT in the Avago booth 6-206 at the PCIM Europe 2015 exhibition in Nuremberg, Germany from May 19^th  to 21^st .

“Built upon a strong foundation with tens of millions of 125°C optocoupler devices shipped into automotive applications, Avago’s latest ACFL family of dual-channel optocouplers can benefit a wide range of high temperature automotive under-the-hood applications,” said Cheng-Dee Lee, business development director of Avago’s Isolation Products Division. “This new dual-channel optocoupler family is an important addition to Avago’s existing portfolio of 125°C optocoupler solutions, addressing the new automotive trend towards high application voltage of up to 1,000V.”
