onsemi FOD8333 Output Current IGBT Drive Optocouplers

onsemi's FOD8333 2.5A Output Current IGBT Drive Optocouplers are an advanced 2.5A output current IGBT drive optocoupler capable of driving medium-power IGBTs with ratings up to 1200V and 150A. They are suited for fast-switching driving of power IGBTs and MOSFETs in motor-control inverter applications and high-performance power systems. The onsemi FOD8333 offers protection features necessary for preventing fault conditions that lead to destructive thermal runaway of IGBTs. 

These devices utilize proprietary Optoplanar® coplanar packaging technology and optimized IC design to achieve reliable high isolation and high noise immunity, characterized by high common-mode rejection and power supply rejection specifications. The device is housed in a wide-body, 16-pin, small-outline, plastic package.

Features

  • Input LED drive facilitates receiving digitally encoded signals from PWM output

  • High noise immunity characterized by common mode rejection - 35kV/μs minimum, VCM = 1500VPEAK
  • P-channel MOSFETs at output stage enable output voltage swing close to supply rail (rail-to-rail output)
  • 15V to 30V supply voltage range
  • Integrated IGBT protection
  • Desaturation detection
  • "Soft" IGBT turn-off
  • 2.5A peak output current driving capability
  • Automatic fault reset after fixed mute time, typically 33μs

  • Fast switching speed over full operating temperature range
  • 250ns maximum propagation delay
  • 100ns maximum pulse width distortion
  • Extended industrial temperate range
    • -40°C to +100°C
  • Safety and regulatory approvals
  • UL1577, 4243VRMS for 1 minute
  • DIN-EN/IEC60747-5-5: 1,414VPEAK working insulation voltage rating / 8000VPEAK transient isolation voltage rating

Applications

  • AC and brushless DC motor drive
