  • Smart Gate Drive Optocoupler with Integrated Flyback Controller
    The new ACPL-302J is a smart gate drive optocoupler that improves isolated power supply and simpli fies gate drive design. The ACPL-302J features an integrated flyback controller for DC-DC converters and a full set of fail-safe IGBT diagnostics, protection, and fault reporting, providing a complete
  • Digital Isolator Evolution Drives Optocoupler Replacement
    Optocouplers are inherently limited by outdated LED-based technology, which exhibits significant output variation over input current, temperature and age. These variations reduce the operating performance and reliability over the optocoupler's lifetime, resulting in increased design complexity
  • Gate Drive Optocoupler Provides Robust Insulation in IGBT Destructive Tests
    Avago Technologies gate drive optocouplers are used extensively to drive IGBTs in applications such as motor drives and solar inverters. Optocouplers are a proven technology to provide reinforced galvanic insulation for high voltage protection between IGBTs and control circuits. They are also used

A brief description. guide or additional applications ranging from power supply and information
  • Isolator vs. Optocoupler Technology
    Optocouplers have been the unchallenged signal isolation solution for over 40 years, but digital isolators fabricated in complementary metallic oxide semiconductor (CMOS) process technology are gaining favor in the design community because of their superior performance, reliability and integration
  • When to Use a Digital Isolator vs. an Optocoupler
    Over the last four decades, optocouplers have been the "default" signal isolation device, but recent breakthroughs in silicon isolation technology have spawned smaller, faster, and more reliable and cost-effective solutions that have already begun supplanting optocouplers in many end applications
  • Optocoupler Performance Comparison: NEC PS9552 vs. Avago HCPL-3120
    Both the PS9552 and HCPL-3120 are optically-coupled isolators that employ a GaAlAs LED on the input side and a photo diode, a signal processing circuit, and a power output transistor on the output side. They feature large peak output current, fast switching speeds, undervoltage lockout protection
  • Overview of NEC / CEL Optocoupler Products for Motor Control Applications (.pdf)
    This paper addresses various applications where NEC/CEL optocouplers offer galvanic isolation for driving MOSFET / IGBT devices in industrial applications including general-purpose inverters, AC servos power switching, home appliances and motor control applications.
