Avago Technologies Introduces Automotive-Qualified Gate Drive Optocoupler for Hybrid and Electric Vehicles
Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced a new automotive-grade optocoupler with extended temperature operation for use in hybrid and electric vehicles, here at the Electronica 2010 trade fair. Increasing consumer demand for hybrid and electrical vehicles with more powerful engines has car makers and their suppliers seeking more robust gate drive optocouplers to help drive higher-capacity engines, as well as battery charger and DC-DC converter systems. The new Avago ACPL-38JT 2.5-Amp optocoupler is qualified to AEC-Q100 Grade 1 stress test requirements, delivering safe electrical signal isolation from -40 to +125° C.
The highly-integrated ACPL-38JT power control device incorporates a complete Insulated Gate Bipolar Transistor (IGBT) driver for signal switching, along with desaturation detection and fault status feedback systems for constant signal protection. The device is part of the Avago R2Coupler™ family of optocouplers with reinforced insulation for reliable signal isolation, which is critical in automotive and high-temperature industrial applications such as isolated IGBT/power Metal Oxide Semiconductor Field Effect Transistor (MOSFET) gate drives, industrial inverters, AC and brushless DC motor drives, and uninterruptable power supplies.

“This newest offering in our R2Coupler family gives Avago the most complete automotive optocoupler portfolio, putting our products in excellent position to grow along with the market for hybrid and electric cars,” said Cheng-Dee Lee, Business and Applications Development Director for Isolation Products at Avago. “More than 40 automotive companies, including car manufacturers and tier one suppliers, are using or evaluating our R2Coupler isolation products. Avago optocouplers are well known for their reliable signal and high-voltage isolation with excellent EMI immunity, with more than 35 years of proven field applications in the military, aerospace, mass-transit and industrial markets.”

During power-up, the ACPL-38JT optocoupler’s under voltage lock-out (UVLO) protection feature protects the IGBT from receiving insufficient gate voltage by forcing lower output. The integrated IGBT gate driver is designed to increase the performance and reliability of a motor drive without the cost, size and complexity of a discrete design. Available in a 16-lead small outline (SO-16) surface mount package, the device is compliant to UL 1577, IEC/EN/DIN EN 60747-5-2 and CSA industrial safety standards.

Avago is exhibiting the ACPL-38JT optocoupler along with a wide range of its isolation, fiber optics, motion control and LED products for the industrial and automotive markets at Electronica 2010 in Hall A4 booth 458 at the New Munich Trade Fair Centre from November 9-12.
