Avago Technologies (San Jose, CA) (Nasdaq:AVGO) has announced a new highly-integrated smart gate drive optocoupler device, the ACPL-339J. The device is a 1 A output current gate drive optocoupler with dual outputs optimized for driving both high-side and low-side gates of the MOSFET buffer stage. Features include:

  • Internal active timing control circuitry.
  • A design to support MOSFET buffer of various current ratings.
  • VCE desaturation (DESAT) detection.
  • Under voltage lockout (UVLO) detection.
  • Isolated open collector fault feedback.
  • A maximum reinforced working insulation voltage of VIORM=1414VPEAK and
  • UL1577 with a maximum insulation voltage of 5 kVRMS.
