Avago Technologies Announces New Line of 14.2mm Optocoupler Devices

Avago Technologies, a leading supplier of analog interface components for wireless, wireline, and industrial applications, today announced a new family of 14.2mm optocoupler devices, the ACNT-Hxxx, designed for high voltage applications.

The ACNT-Hxxx family consists of three major product series: the ACNT-H3xx, high efficiency gate drive optocouplers for driving IGBTs; the ACNT-H6xL, low power 10MBd digital optocouplers for system control and data communications; and the ACNT-H79x, high linearity isolation amplifiers for current and voltage sensing applications.

ACNT-Hxxx Highlighted Features and Benefits

  • Safety Approvals for CSA, UL and IEC
    • IEC/EN/DIN EN 60747-5-5: VIORM = 2,262 Vpeak
    • UL1577: VISO = 7,500 Vrms
    • Robust, reliable and fail safe reinforced insulation
  • 14.2mm Creepage and Clearance
    • Industry's highest insulation voltage in compact 14.2mm SSO-8 package
    • Meets stringent system and equipment regulatory requirements
  • High Gate Driving Current and Noise Immunity (ACNT-H3xx)
    • Minimum 2A output current for driving IGBT
    • Minimum 40kV/µs CMR at VCM = 1.5 kV minimizing erroneous signals in driving IGBT in noisy environment
  • Low Power Consumption (ACNT-H6xL)
    • Less than 20 mW
    • Industry's lowest power 10MBd optocoupler in compact 14.2mm SSO-8 package
  • Excellent Linearity and Gain Accuracy (ACNT-H79x)
    • Advanced sigma-delta A/D modulation technology with full differential isolation
    • 0.05% linearity and -50ppm/°C gain drift for enhanced accuracy

"High-voltage power systems today require chip-level components to support well insulated and noise-immune large signals to minimize copper wiring costs while maintaining optimal power efficiency," said Kheng-Jam Lee, marketing director of Avago's Isolation Products Division. "Avago has stepped up to the challenge with the introduction of a new 14.2mm optocoupler family. With the industry's highest insulation voltage in compact SSO-8 footprint, the ACNT-Hxxx is the most complete and cost-effective set of high-voltage optocoupler solutions on the market today addressing a wide range of high power industrial applications including inverters, motor drives and power supplies."
